Aperiodicwaveforms with mismatched filtering for target detection in heavy clutter. part II - MIMO radar architecture

Yuri I. Abramovich, Geoffrey San Antonio, Gordon J. Frazer

Abstract

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 applications. It has been recently demonstrated that periodic waveforms currently used in HF-OTHR for efficient ground clutter mitigation have very limited scope for MIMO radar applications. This is due to the fact that the sidelobe-free area in the appropriate MIMO ambiguity function is K times smaller than for a single periodic waveform, where K is the number of MIMO waveforms.
