摘要

提出了一种基于时频表示和Viterbi算法的雷达信号检测方法。考虑了短时傅里叶变换(STFT)和s -法(SM)两种TFR方法。在加高斯噪声、信噪比为- 15 dB ~ - 2 dB的单机动目标真实雷达信号中，研究了该算法的性能和检测能力。结果表明，即使在很低的信噪比下，该算法也能很好地工作。

An algorithm for detecting a maneuvering target based on TFR and Viterbi algorithm

An algorithm for radar signal detection method based on a time-frequency representation (TFR) and Viterbi algorithm (VA) is proposed. Two TFR methods are considered, Short-time Fourier Transform (STFT) and S-method (SM). Performance and detection ability of the proposed algorithm was investigated on real radar signals of a single manuvering target with added Gaussian noise and signal-to-noise ratio from −15 dB to −2 dB. The results show that the proposed algorithm works well even in very low SNR values.
