To improve the accuracy and to speed up calculation the decimal coding, tournament selection and optimal individual record are adopted. 采用十进制编码、竞争繁殖和逐代记录最优法来加快计算速度和精度;
Usually, the value of a in this method is a subjectively given decimal, and can not offer optimal recognition results in varied clutter environment. A new a truncation set feature extraction based method with adaptive selection of a is proposed. 通常α截集特征提取方法中的α值是主观给出的一个小数,在多变的雷达杂波环境中不能使α截集特征提取方法给出最佳的识别效果。
According to actual computing, decimal integer code equivalent to vector is designed, as well as double-objective fitness function, corresponding probability for selection, mutation and cross. 根据实际运算的需要,设计了与测试向量等值的十进制整数编码;设计了相应的双目标适应度评价函数以及选择、变异和交叉概率。
