摘要
提出了两个提高成像效率的方法 ,即选取特定的距离单元来进行方位聚焦和通过一定的预处理 ,使得能够直接应用FFT来实现方位聚焦 ,并编制成像程序 。
Two methods are presented to improve the imaging efficiency.One is that special range cells are chosen according to actual needs,to participate in the following processes.The other is that some pre-treatments are done to every range cell to make cross-range fast Fourier transform(FFT) feasible.In addition,a program is designed to realize the imaging process and it is testified to work well by simulation data.
