Systems Integration
  Warner Robins Air Force Base -- JSTARS Security System
Developed for: United States Air Force (USAF)
This project comprised a multimillion dollar system integration contract awarded to L-3 Communications GSI to protect the Joint Surveillance and Target Attack Radar System (JSTARS) aircraft assets in Warner Robins, GA. Patrick Cesarano of Cesarano Technologies, Inc. served as lead engineer on the project, which incorporated video motion detection, short and long range RADAR, entry control, motion, pressure, fence and BMS sensors, over 70 video assessment and 30 data feeds, RS-232/422 control protocol nodes, 3-DES encryption and full integration into a proprietary fiber-backbone XML network.

Cesarano Technologies, Inc.
conceived and introduced a novel,innovative approach to base security. By treating each physical security point as a digital state (alarmed or secure, or 0/1), we were able to treat the entire base as a scalable VLSI/ULSI integrated circuit, allowing us to introduce modern circuit design technologies incorporating logic and discrete algorithms to optimize security-related communications across the base, the effect of which was increased reliability, stability and control. This strategy also lent itself to footprinting primary signal paths (through buildings, switches, etc.) illuminating areas in need of enhanced resource allocation and providing a transparent signal "skeleton" for diagnosing system vulnerabilities/weaknesses. The design required over a dozen sub-contractors and took five years to fully design and assemble--the aim of this effort was to incorporate all base security events into a prioritized, accessible queue tagged by video, still shots, time-stamped records and an operator's documentation. A secondary feed was also provided for a remote (redundant) system operator. Mr. Cesarano also served as the principal architect of the field programmable gate array sensor interface server (FPGA-SIS) responsible for all sensor monitoring and XML annunciation, and further designed the line-supervision circuits used to detect tamper and spoof on all copper and fiber lines.

  Vortex
Developed for: White Sands Missile Range (US Army-WSMR) and the University of New Mexico
This project aims to detect transceivers used in the coordination of IED attacks by looking for signal by-products created during the normal operation of constituent non-linear (semiconductor) components operating in an otherwise linear medium (rocks, trees, etc.). It does so by scanning all standard communications frequencies (0-11 GHz) with a proprietary waveform-- at the IED's tuned antenna frequency this signal couples into the device generating its unique signature, which is subsequently identified at a separate receiver. This not only signifies its presence but provides crucial information as to the device's operating frequency, which can then be saturated (jammed), cutting off all external signaling—at this point the supporting forces can simply switch to neighboring communication channels while the device is disarmed.

This process has been demonstrated to work even when the devices are powered off, and for ANY wireless transceiver device including cell phones, laptops with WiFi, walkie-talkies, and even receive-only devices such as GPS units and digital radios. The second illustration (below) shows expansion markets for this technology--areas where smart devices with cameras or other recording capability may be prohibited such as airports, power plants, court houses, etc.

  USMC and General Dynamics -- "Smart" Light Armored Vehicle (LAV) Prototype
Developed for: The United States Marine Corps (USMC)
This project aims to harness recent technological advances to overcome multiple practical shortcomings in current LAV systems design and further revolutionize the way current subsystems are utilized. It does so by adapting the vehicle and its equipment to a 100% Ethernet Gigabit video/data/control backbone. This solution is especially elegant as future scalability is essentially unlimited. The primary objective is to increase the situational awareness for the support troops stationed in the vehicle's rear, allowing them to switch between multiple digitized video feeds (i.e. the vehicle's primary weapon, secondary weapon, low-light or thermal imaging systems, situational awareness camera, GPS locator or any other video feed/GUI incorporated in or on the vehicle). It gives this same access to the LAV driver and navigator, each of whom currently has an independent hardware reticle available to them alone. While the prototype currently supports only (passive) video, the Ethernet protocol would allow for future development into active passenger or remote operator subsystem observation and/or control, possibly within a dedicated to-be-specified software layer.

  Gaussian Mean Phase Shift Keying Modulator (GMPSK) with Pseudorandom Noise (PN) Ranging "Soft Models"
Developed for: NASA Goddard Space Flight Center
This project comprised a 6-month effort to develop MATLAB "soft models" for the existing communications hardware architecture at the Goddard Space Flight Center, verify they correlate with actual measured data, and then suggest and test modifications and improvements. The simulation models allow for extensive testing and development prior to (or in many cases in place of) financially exorbitant field testing (testing on payloads in space). These models in particular simulate a proposed GMPSK modulated data signal combined with a PN ranging tone designed to address emerging requirements for simultaneous high data rate with tracking (ranging) capability. GMPSK is just a variant of frequency shift keying (FSK) like FM and is the main data carrier. PN code is a close relative of the code division multiple access (CDMA) scheme used by cellular phones—it is as close to noise as is mathematically possible while still retaining information (in this case, the smaller ranging tone) and is decoded by a unique bit vector also nearly orthogonal to all other neighboring signals.

  RF Component Modeling in ADS, Sonnet, MATLAB and HFSS
Developed for: Virginia Diodes, Inc., JPL, Caltech, NRAO, Oleson Microwave, Raytheon, NASA-Goddard, others
HFSS and Son-nett are finite-element electromagnetic simulators solving the discretized Maxwell equations in 3 and 2.5-D structures, respectively. ADS is a harmonic balance simulator allowing small-signal modeling of active components and circuits. Together, they form the backbone of the RF component industry--our knowledge and experience with these powerful tools cannot be understated.

Simulators at work:
The slides below illustrate the tremendous utility of various simulators working alone and in conjunction with each other. In the first set, Sonnet uncovered unwanted electromagnetic (B-field) coupling in a 20 mil (2/100 in.) cavity resulting in shorter trace electrical lengths. The new effective lengths result in a tuned circuit of higher frequency (10 dB less magnitude at the low end (40 GHz) of the design frequency). This problem was fixed by redesigning the chassis with an extra 11 mils (11/1000 in.) of z-clearance--small, but enough to fix the problem:

In this next set, ADS predicted superior insertion loss in a frequency multiplier by tripling each of the anti-parallel diodes. In practice, the distances between them could be no closer than 42 mils (42/1000 in.) by Raytheon foundry standards--Sonnet predicted horrible phase mismatch with these spacings and the circuit ceases to be operational. A MATLAB simulation of the 42 mil spacings (below) confirmed this conclusion. A compromise was reached wherein Raytheon agreed to space the anodes by only 10 mils (1/100 in.) in a Cesarano Technologies, Inc. hybrid "three fingered" Schottky diode with a single cathode. The functionality of the anode spacings in the new design was confirmed by Sonnet and MATLAB (below), and the performance turned out to be exceptional. Following their fabrication and testing, the new devices were so successful they becomes Caltech's standard for frequency multiplication, mixing, and a variety of other applications—they (and their new architecture) have replaced the old design in literally thousands of circuits (below).

  Link Budget Analysis
Developed for: United States Customs and Border Protection (USCBP), United States Air Force (USAF)
Link budget and coverage analysis has seen tremendous advances in the accuracy and reliability of calculations with the incorporation of United States Geological Survey (USGS NED 1/3 Arc Second) data via the "Seamless Data Warehouse". Cesarano Technologies, Inc. was privileged to work with L-3 Communications, GSI on a proposal evaluating operating frequencies for US Customs and Border Protection at southern border stations at 2, 7, and 15 GHz. We also contributed simulations and analysis to a proposal for the USAF which suggested using a redundant ring architecture between launch facilities (LFs) and their coordinating master facility (MAF) for North American Minuteman ICBM silos and evaluating the feasibility of these RF links over satellite with the conclusion that 2/3 of the United States could be sufficiently serviced with terrestrial links alone.

  Stock Predator: Real-Time Trading Analysis Software
Developed for: Private Party Customer
Cesarano Technologies, Inc. has undertaken a number of software development projects in addition to its mainly hardware-oriented focus. This software suite works in real time with incoming stock quote data to perform a variety of traditional mathematical analysis strategies on any publicly traded company of interest. It utilizes a pricing feed available only to licensed Wall St. traders, and was developed with only a house simulation of this feed. It was painstakingly coded to work as fast as possible--it is bare-bones other than its unique purpose, and further implements a number of code-intensive sub-routines which are were verified to work faster than equivalent look-up table strategies. It was developed for a private party to give them a technological edge over fellow traders using otherwise comparable software.
