Abstract :
In order to analyze the time-frequency property of sparse sample data, the STFT algorithm and Gabor transformation algorithm based on compressed sensing are proposed. Compared with traditional algorithm, they have lower side-lobs in time frequency domain. Data processing validates the effectiveness of the algorithms in micro-Doppler signature analysis and manoeuvre targets ISAR imaging.
