Detection and parameter estimation of intra-pulse modulated radar signals in complex interference environments+

Abstract The main aim of this review is to describe in detail an advanced technique detect and estimate the prior unknown parameters intra-pulse modulated signals verification with typical radar signals. method approved for detecting successfully, including chirp rate, carrier frequency, pulse width. presents already-done research on estimating single multi-component linear frequency modulation (LFM) binary phase shift keying (BPSK) a strong noise environment studies one more case, mixture LFM BPSK Firstly, accuracy revised shown signal white continuous wave noise, or noise. All them have been done existing studies. This continuously tested second part by their intense experimental results demonstrate that can real-time signals, as well $$SNR \ge - 12{\text{ dB}}$$ S N R ≥ - 12 dB performed. As result, outperforms detection methods based machine learning artificial intelligence.
