Coherent integration with backprojected images for near field moving target
A signal may not be detected and identified due to the presence of serious noise. Coherent integration is an important approach for focusing the energy of the signal in pulse-Doppler radar. For moving targets, the problem of migration through range cells (MTRC) will degrade the coherent integration result. This paper presents a new coherent integration method for multi-channel radar system to focus near field moving targets. The envelope correction coupled with backprojection in spatial and fast-time domain is performed, followed with coherent integration in slow-time domain. The simulated results demonstrate the effectiveness of the method in target detection.
