Case  1: simulated data as radar output directly.
Case  2: add Gaussian white noise to simulated data as radar output with SNR of 30 dB.
Case  3: add Gaussian white noise to simulated data as radar output with SNR of 20 dB.
Case  4: add Gaussian white noise to simulated data as radar output with SNR of 10 dB.
