ABSTRACT:
An interferometric moving target radar imaging system includes a plurality of simultaneously operating apertures, receivers and processing channels which together coherently process RF return signals to image a moving vehicle. The system corrects for the different phase centers of the apertures and interferometrically combines the return signals from different apertures to attenuate the energy from stationary objects. The true azimuth location of the moving vehicle within main beam clutter spread is then determined which facilitates distinguishing between slow moving and stationary objects to detect the moving objects which are then tracked and imaged in the range doppler domain.
