摘要
针对利用单双站等效法存在的大角度双站雷达散射截面计算误差太大的问题和用被光照面作为积分区域计算双站雷达散射截面方法存在的无法处理相对接收站可见面的识别问题,从感应定理和等效原理出发,基于图形电磁计算方法,提出了双站雷达散射截面图形电磁算法的改进方法,解决了可见面的识别问题,扩大了感应定理和等效原理的应用范围,提高了双站雷达散射截面计算的准确度。通过对典型样件的计算结果比较与公认结果和解析算式结果一致,证明了该方法的有效性。
Based on the induction theory,equivalent theory and graphical electromagnetic computing meth od, an improved method of graphical electromagnetic computing method to compute bistatic RCS is presented, and the disadvantages of methods of single-double station equivalent method and using the faces illuminated by the light as the integral area to compute the RCS are overcome. The problem of being not able to check the face which is able to be saw by receiving station is overcome, the used range of induction theory and equivalent theo ry is widen and the accuracy of the computing bistatic RCS is improved. By comparing the computing results of typical object with the commonly accepted results and results based on analytic formula, it is proved that the re suits using the method presented in the dissertation is valid.
