Fast Implementation of Chirp Scaling Imaging Algorithm Based on GPU
摘要
Abstract
A parallel chirp scaling(CS)imaging algorithm based on graphic processing unit(GPU)is proposed for multi-re?ceiver synthetic aperture sonar(SAS),which provides a new method of real-time imaging for SAS. The echo transformation,azi?muth and range FFT transformation,and point multiplication of CS algorithm for SAS are designed parallel in GPU environment. The imaging results for the real echo of synthetic aperture sonar show that the parallel CS algorithm keeps the high precision of SAS imaging result and the speedup reaches 56.25,which makes it meet the demand of SAS system for real-time imaging.关键词
