Complementary Frequency Modulated Radar Waveforms And Optimised Receive Processing

Design methodologies are developed for complementary frequency modulated (FM) waveforms and for optimised complementary mismatched filtering (MMF) of arbitrary non-repeating waveforms. The former is a sub-class of random FM waveforms denoted as complementary FM (Comp-FM) while the latter extends a practical instantiation of least-squares mismatched filtering yielding the mismatched complementary-on-receive filtering (MiCRFt) scheme. Both of these approaches have an emphasis on the non-ideal physical effects of the radar transmitter and receiver, thereby permitting high-fidelity simulation analysis and subsequent experimental demonstration of their efficacy using open-air measurements.
