| 摘 要： | UWB-SAR系统较之常规SAR系统,成像所需计算量更为庞大,实时处理的实现更难.通过将子孔径思想应用于BP算法,给出了一种实用的实时成像算法(LocalBP算法),该算法同BP算法相比,成N×N点的图像,运算量可减少,同时该算法具有良好的并行及流水实现结构.

| Abstract: | Compared with usual SAR, the computational load of UWB SAR system for imaging is larger, and the realization of real time processing is more difficult. According to applying sub aperture process to the BP algorithm, a practical real time imaging algorithm(Local BP algorithm) is presented. For a SAR image area with N pixels each side, LBP algorithm can reduce the required operations, and it has a good parallel and pipelined architecture. |
