Moving target detection method of the Ka FMCW SAR based on DPCA

In the paper, the traditional Displaced Phase Center Antenna (DPCA) combines with the triangular wave FMCW to detect the moving targets, which could make the single-channel equivalent to the dual-channel. Without requiring any additional system instruments, cost and light, the miniaturization Ka FMCW SAR system could own the moving target detection function. This method is simple and applicable. In addition, the corresponding principle and processing procedure are all given. Based on the real data, the method is verified effective and feasible.
