MIMO SAR Imaging for Wide-Swath Based on Compressed Sensing

Figure 12

The beam patterns with different SNR and INR. (a) shows reconstruction in the case of SNR = 5 dB, INR = 10 dB, (b) shows SNR = 5 dB, INR = 40 dB, (c) shows SNR = 10 dB, INR = 10 dB, and (d) shows SNR = 10 dB, INR = 40 dB.

(a) SNR = 5 dB, INR = 10 dB

(b) SNR = 5 dB, INR = 40 dB

(c) SNR = 10 dB, INR = 10 dB

(d) SNR = 10 dB, INR = 40 dB
