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

摘要

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.
