Abstract
En 中文
The complementary waveform-based moving target detection faces challenges like limited Doppler resolution and poor range sidelobe suppression. This letter proposes a Complementary-Moving Target Detection (C-MTD) method to address the coherent integration issue of Waveform-Domain Complementary Signal Sets (WDCSS), a subset of generalized complementary waveforms. C-MTD enhances Doppler resolution and extends complementary properties to the range-Doppler map by applying coherent slow-time processing to consecutive WDCSSs. Simulations demonstrate that C-MTD outperforms conventional methods in Doppler resolution, range sidelobe suppression, and detection under low input signal-to-noise ratios (SNRs) conditions.
