Abstract

A DPCA (Displaced Phase Center Antenna) approach based on digital all-pass interpolation of array elements for side-looking phased array radar on moving platforms is proposed, this technology employs a class of maximally flat digital fractional-delay systems to realize interpolation of array elements followed by DPCA processing, and it does not require conventional DPCA condition. It is shown by the results of simulation that this technology exhibits good GMTI (Ground Moving Target Indication) performance, so it can be used as a good choice of GMTI technologies for airborne or space-based phased array radar.
