Compressive sensing radar imaging under low SINR via waveform optimization

To enhance the performance of compressive sensing radar (CSR) imaging in low SINR, a waveform optimization method at the transmitter, instead of processing signal at the receiver, is proposed. The method can effectively improve the CSR range-Doppler imaging quality and reduce the target range-Doppler parameter estimation error in low SINR. Simulation results show the effectiveness of this method.
