Analysis of Moving Object Imaging from Compressively Sensed SAR Data in the Presence of Dictionary Mismatch

Table 2

Effect of mismatch on range and azimuth positions.

Mismatch type	Effect in range	Effect in azimuth
Range	Δ𝑟𝑛	−Δ𝑟𝑛(Δ𝑣^𝑘𝑥/𝑉)sin𝜃𝑛
Azimuth	Δ𝑦𝑛(Δ𝑣^𝑘𝑥/𝑉)sin𝜃𝑛	−Δ𝑦𝑛
Velocity	𝑦𝑛(Δ𝑣^𝑘𝑥/𝑉)sin𝜃𝑛	−𝑟𝑛(Δ𝑣^𝑘𝑥/𝑉)sin𝜃𝑛
