摘要

合成孔径雷达(SAR)成像处理是一项复杂的操作，需要进行大量的浮点运算。在微机上将SAR原始数据转换成图像非常耗时。作者先后采用国产分布式存储多处理器架构的jn3ar和可扩展共享存储多处理器架构的SGI Origin 200两种计算机开发了SAR处理器。大大提高了SAR成像效率。

Parallel programming in SAR imaging processing

Synthetic aperture radar (SAR) imaging processing is a complex operation that requires a large amount of floating point computations. It is very time-consuming to convert SAR raw data into imagery on microcomputers. The authors have successively developed SAR processors using two kinds of computers-JN3AR of distributed memory multiprocessor architecture (made in China), and SGI Origin 200 of scalable shared memory multiprocessor architecture. The SAR imaging efficiency has been greatly improved.
