An Overlapped Subaperture Polar Format Algorithm Based on Sub-chirp Signals

摘要：

In this work,a 2-D subaperture polar format algorithm (PFA) based on stepped-chirp signal is proposed. Instead of traditional pulse synthesis preprocessing,the presented method integrates the pulse synthesis process into the range subaperture processing.Meanwhile,due to the multi-resolution property of subaperture processing,this algorithm is able to compensate the space-variant phase error caused by the radar motion during the pulse cluster. Point target simulation has validated the presented algorithm.
