MIMO SAR Imaging for Wide-Swath Based on Compressed Sensing

Figure 9

The spectrum of reconstruction in different SNR. (a) shows that the reconstruction in the case of SNR = 20 dB, (b) shows SNR = 15 dB, (c) shows SNR = 10 dB, and (d) shows SNR = 5 dB.

(a) SNR = 20 dB

(b) SNR = 15 dB

(c) SNR = 10 dB

(d) SNR = 5 dB
