Time-space correlation-based Video SAR moving target detection method

The invention discloses a method for detecting a moving target of a Video SAR (Synthetic Aperture Radar) by utilizing space-time correlation. The method comprises the following specific steps of: step1, carrying out shadow detection on a single frame image of the Video SAR by adopting a basic static shadow detection model; step 2, obtaining a target motion parameter by adopting a matching searchmode, and obtaining a motion target estimation speed; step 3, carrying out track tracking on the moving target through a Kalman filtering tracking algorithm, and preliminarily screening a real movingtarget by using a track association method; and step 4, tracking the target in the step 3 by adopting a space-time correlation method, comparing the distance between the centroid of the shadow area ofthe first frame of image and the shadow area of the last frame of image and a given threshold after a period of time, and screening a real moving target shadow. Static shadows are removed from a high-probability moving target s
