Principles of MIMO radar based on ultrawideband throb signals

This paper describes the principles of multiple-input-multiple-output (MIMO) radar operating with a set of quasi-orthogonal ultrawideband (UWB) throb signals. MIMO radar ambiguity function (AF) is derived for the UWB-throb signals, and used to generate plots of delay-Doppler resolution function, delay-angle resolution function, Doppler-angle resolution function, and MIMO power beam-pattern for system and signal design parameters. The MIMO ambiguity function is an important tool that facilitates the process of signal design and diversity for achieving improved radar performance in terms of target detection, high-resolution imaging, target identification, and clutter suppression.
