Herein, a solution is presented to address the problem of providing scalable dynamic spectrum awareness for military (and commercial) applications opportunistically using RF devices that are deployed for tasks other than spectrum mapping. We consider challenging urban environments with a large heterogeneous mix of devices and signals. Additional challenges we address include sparsely distributed receivers...
Several types of passive receivers can be used to detect radar emissions over considerable distances. Previous work has been performed which compares the detectability of bi-phase waveforms to a classic rectangular pulse. It is also of interest to compare the detectability of equal-bandwidth/equal-energy FMCW, quadriphase, and polyphase waveforms. The quadriphase waveform is the quadriphase version...
