Abstract

To realize the target classification, recognition and imagery, it is necessary to research its micro-Doppler (m-D) effect. The m-D signals are usually submerged by strong body echoes. In this paper, extraction of m-D information under the condition of low signal-to-noise ratio (SNR) was studied. An algorithm for elimination of body's signals and extraction of m-D features in the "spectrogram" domain was proposed. The simulation shows the method is satisfactory even with SNR=-50dB.

Key words： micro-Doppler; low signal-to-noise ratio; Hough transform; target recognition
