Moving targets appear seriously degraded with smearing
defocusing and apparent shifts in the azimuth direction in Synthetic aperture radar (SAR)images and give rise to a considerable loss of the target-to-clutter ratio (TCR).This paper proposes a method to detect moving targets in single-channel SAR single look complex (SLC)image based on sub-aperture decomposition technique.The method can suppress the clutter by image subtraction between two sub-aperture images
therefore enhance the TCR.The effectiveness of the method is demonstrated on airborne Convair-580 data and Envisat ASAR data.
