摘　　要：针对编码基因的多弹头落点激波定位算法中需要设定敏感系数以及存在虚假基因等问题,利用同一弹道线上四个点所决定的各矢量之间的夹角关系,对原算法进行了改进。该算法通过定义判决系数来提取满足要求的编码基因,当编码基因矩阵里的编码基因全部提取完毕时即可将正确的基因用于落点定位。仿真表明:该改进算法能够避免原算法中敏感系数因弹丸数的改变而需重新设定所带来的不便,以及程序因弹丸数过多而出现死循环的现象。The multi-warhead impact shock wave location algorithm needs to set sensitivity coefficient and has false genetic code. Aiming at these problems, the relationship of angles between vectors which were determined by four ponits on a same trajaetory was taken to improve the former algrithrru The improved algorithm extracted the genetic code which satisfied the requirement by defining judging coefficient. The right genetic code could be uesd to locate the falling point until all the genetic codes in the genetic code matrix were removed. The inconven-ience of resetting sensitivity coefficient when the number of warhead changed and the phenomenon of endless loop appeared in the program for superabundant warheads were avoided. Computer simulation showed its effec-tiveness.
