Expected Likelihood based quality assessment of DOA estimates relies on the underlying signal and noise distributions having likelihood ratio probability density functions for the (unknown) true parameters that are independent of the actual true DOAs. This has been shown, both analytically and pract…
Periodic waveforms used for most radar operations in heavy clutter often suffer from range-folding and/or Doppler frequency aliasing effects. Aperiodic waveforms with a “thumbtack” ambiguity function do not have range and/or Doppler ambiguities, but due to the relatively high sidelobe levels cannot…
In a companion paper we have investigated the applicability of aperiodic noise-like waveforms with a “thumb-tack” ambiguity function processed using mismatched compression filters for strong clutter rejection. In this paper we investigate the role of the same principle in mode-selective MIMO OTHR ap…
