UHF waveband SAR GMTI moving screening method

The invention discloses a UHF waveband SAR GMTI moving screening method. The method comprises sequentially executed following steps: a step I, SAR imaging processing is performed on echo data of multiple channels through adoption of an omega-K algorithm, a step II, registration is performed on SAR images which are formed by the various channels and obtained in the step I to obtain the SAR images after the registration, a step III, clutter suppression is performed on the SAR images after the registration, and a suspicious target is detected, a step IV, a Doppler phase history of the suspicious target is recovered, a step V, reimaging the suspicious target, a step VI, whether the suspicious target is a moving target is judged according to the regenerated image of the suspicious target, and a step VII, parameter estimation and relocation processing are performed on the target. According to the method which recovers the target Doppler phase history in the SAR image by utilizing the omega-K algorithm, original data are provided for subsequent target imaging, and moving target identification of a UHF waveband is achieved.
