Abstract

Abstract

SAR/DPCA(Displaced Phase Center Antenna) technique is a simple and practical method of multi-channel SAR/GMTI(Graund Moving Target Indication), but in practice it is limited by some kinds of errors, in which antenna phase center velocity error and channel mismatch are the most important errors. In this paper, the error analysis model is founded and the loss of moving target detection performance is analyzed under the circumstance of antenna phase center velocity error or channel mismatch. The error analysis results are shown on the figures and the range of detectable velocity, blind velocity and minimum detectable velocity are confirmed on the basis of actual parameters of dual-channel SAR/DPCA system.
