The problem of ground moving target imaging and detection is difficult due to the large range cell migration (RCM) and time-varying Doppler frequency migration (DFM) in synthetic aperture radar (SAR) system  ...  In this work, an efficient ground moving target refocusing method based on pseudopolar fast Fourier transform (PPFFT) and coherently integrated cubic phase function (CICPF) is proposed without a priori  ...  In recent years, many approaches have been proposed to obtain the image of ground moving target with SAR system, and they can be mainly classified into four groups.  ...

DPCA-SAR is a single-pass collection platform where, in effect, two SAR images, having only a temporal sepa- ration, are combined to provide a ground moving target indicator (GMTI) system.  ...  Since the collection platform is moving, all objects in the ground scene are going to create a Doppler shift on the incident signal.  ...  Recall target displacement is 1 mm cvp = 1e-6/2; % co-variance of the target position In these simulations we assume the prf is significantly faster than the target's vibration fequency.  ...
