Study of Anti Jamming of Radar Signal Based on Sparse Decomposition

In order to distill the features of radar echo-signal affected by strong jamming noise, the sparse decomposition method and BPDN (Basis Pursuit Denoising) algorithm are used to remove the noise and recover the radar echo-signal. Based on the theory analysis, the reconstruction of the radar echo-signal with different SNR and anti-jamming effect of the method is studied by the simulation. The simulation results show that the proposed method is effective for anti-jamming of radar signal.
