Waveform agile MIMO radar fast waveform design based on random arrangement of pulse slices

This paper introduces a novel waveform agile MIMO radar waveform design method based on random arrangement of pulse slices (RAPS), enhancing the conventional Frequency diversity LFM (FD-LFM) transmit beampattern synthesis. We conduct a pioneering analysis of the auto-correlation function characteristics of the existing FD-LFM, revealing theoretical insights into its low range resolution and associated factors. The proposed method significantly enhances range resolution and effectively minimizes range sidelobes by combining RAPS and waveform agility between pulses. The efficacy of this approach is corroborated through comprehensive simulation experiments.
