Abstract :
In order to enhance the moving target detection performance of airborne SAR, a virtual tri-channel displaced phase center antenna (DPCA) approach based on increasing radar echoes´ channel using equivalent phase center approach is proposed in this paper. The echoes´ characteristic of actual aperture and virtual aperture is analyzed firstly. Then, the compensation to virtual aperture channel in order to realize virtual tri-channel DPCA, the compensation is given and analyzed and the processing frame of moving target detection of airborne SAR based on virtual tri-channel DPCA approach is established. The theoretical analysis and simulation results show the new algorithm is effective and the detection performance is superior to the traditional DPCA algorithm.
