The SCA Technica team, with subcontractor General Dynamics C4 Systems and consultant Dr. Harvey Woodsum, propose to design and build a soldier-borne, small, lightweight, low power, LPI, wide band, quadrant and specific azimuth detector for GPS, combat net radio, and other jammers/emitters. We base our design on our SCA compatible Smart Radio, being developed under SBIR AF03-098 Phase II. We will further leverage the SCA waveform component architecture being developed under SBIR Phase I AF05-108 and NIST 9.05.3-9. As prime contractor for JTRS Cluster 5, GD C4 Systems is ideally qualified to assist us in evaluating RF front end requirements for the proposed Soldier EW Smart Radio. Our hardware and software will be ported to a hand-held computer and integrated with a Cluster 5 compatible wideband 2-channel RF receiver and wideband meander line antenna array. We demonstrate EW algorithms, such as virtual demodulation, hop and chip rate detection and cyclostationary correlation using software downloads. Virtual demodulators detect, classify, and demodulate multiple signals. Rate detectors and cyclostationary correlators detect and parametrize spread spectrum and hybrid waveforms. In combination, multiple conventional and spread spectrum waveforms can be detected, classified, dehopped/despread, and demodulated on the fly, then analyzed and displayed to the Warfighter.
