AbstractThe 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 f?" 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.
