Abstract 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.
