Abstract

Abstract

SAR with Displaced Phase Centers multibeam in Azimuth (DPCA) can solve the confliction between swath width and resolution, but this mode is one Pulse Repetition Frequency (PRF) restriction. In this paper, the spectrum of the signal in the azimuth direction is analyzed, and the reconstruction method of the uniform spectrum in azimuth is given when PRF deviated from the ideal PRF. DPCA with PRF alterable mode is introduced. The simulation of point target is used to analyze the effect of this new method.
