Performance analysis of long-time coherent integration for moving targets

Pulse integration technology is widely used to enhance signal-noise-ratio (SNR) for moving ground target detection in Synthetic Aperture Radar and other radars systems. In this paper, the performance of pulse integration of moving targets accounting for target motion errors is analyzed. For the long dwell time condition, the effects of time-variant motion of targets are analytically discussed. The analytical estimation of biased and unbiased compensation residual errors for targets motion is derived. The estimated results show that the biased and unbiased residual errors can lead to significant performance degradation as the dwell time increases.
