Analysis of Moving Object Imaging from Compressively Sensed SAR Data in the Presence of Dictionary Mismatch
Figure 5
Effects of azimuth pixel mismatch using CSLP and CSGBP.
(a) Effects of azimuth pixel mismatch using CSLP. Only one position is identified correctly with a velocity of 3 m/s
(b) Effects of azimuth pixel mismatch using CSLP. The scatterers are identified at a velocity of 4 m/s, instead of a velocity of 3 m/s. Scatterers are also shifted from their true positions
(c) Effects of azimuth pixel mismatch using CSGBP. The positions are identified correctly with the presence of higher side lobes
