Abstract

In this paper, a method for suppressing range ambiguity and folded clutters is considered. A waveform design method, which adopts linear frequency modulation (LFM) pulse train based on pulse width agility, is proposed. The optimized pulse train, which is obtained by constructing pulse width agile waveforms and optimizing through dynamic programming, has good performance on suppressing range ambiguity and folded clutters. Besides, after joint mismatched filtering, the pulse-Doppler (PD) processing result of the pulse train shows excellent characteristics in both range and Doppler dimensions. Simulation results are provided to verify the effectiveness of the proposed method.
