Abstract :
Element-interpolation DPCA (Displaced Phase Center Antenna) employs a fractional delay filter to get good GMTI(Ground Moving Target Indication) performance while conventional DPCA conditions cannot be met. Its GMTI performance seriously depends on the adopted filter. This paper evaluates 4 fractional delay filters in element-interpolation DPCA, and provides guidelines for choosing an appropriate filter to get best GMTI performance (ICCCAS´07).
