Abstract :
Squint SAR image formation has promising application foreground. In this paper, firstly we proposed a squint SAR image reconstruction algorithm which based on the SPECAN algorithm. The novel method has the characteristics of less calculation, high velocity, high efficiency, wide squint angle range, and etc. Then we corrected the fan-shaped distortion of the reconstructed image. Lastly, this paper analyzed causes of the image geometric distortions and presented a way to correct these distortions.
