Controlled Bandwidth Transmission Systems for Ultra-Wideband Radars

The problem is that current high resolution penetrating RF sensors are incapable of reliably detecting obscured/buried threats to human life, and both military and civilians are dying as a result. Moreover, the high costs and productivity losses caused by destructive testing make this topic of extremely high importance. This SBIR addresses the key element that drives the performance – the waveform, its generator, and the algorithms that compress it. ASI proposes an innovative solution with high technical merit as it (1) mitigates range ambiguities; (2) minimizes sidelobes for a given resolution, (3) minimizes the power consumption, (4) minimizes harmful interference to other radio systems; (5) minimizes the radiated power required to achieve a given SNR; (6) maximizes the dynamic range; (7) suffers the least SNR loss with motion, (8) is ultra stable so as to allow high performance coherent change detection over day/week time frames; (9) provides a user programmable spectrum (a) to spectrally notch frequency bands to avoid interference within any particular theater of operation and (b) to match different missions (e.g. imaging people through a wall versus detecting a weapons cache buried 3 ft underground), and (10) offers new compression algorithms that offer low sidelobes, even with spectral notches.
