最长公共子序列的个人实验，输入两个不同的字符序列（要求必须是字母），将输出这两个字符序列的最长公共子序列。(Individual experiments longest common subsequence, enter two different sequences of characters (letters must be required), the output of the longest common subsequence of the two-character sequence.)

设雷达信号是码宽为0.5微妙，中心频率是10MHz的7为巴克码2PSK信号，接收的雷达回波中频采样频率为为40MHz，中频进行正交下变频。假设在13.5km处有一个点目标，仿真该雷达的脉冲压缩处理。 已通过测试。 (Let the radar signal is yards wide 0.5-subtle, the center frequency of the the Buck the code 2PSK signal, the received radar echo IF sampling frequency of 10MHz to 40MHz, IF quadrature down-conversion. Assuming the 13.5km at a point target simulation of the radar pulse compression processing. Has been tested.)
