序列信号发生器：
在系统时钟的作用下能够循环产生一组或多组序列信号的时序电路，（循环产生一组序列信号0111010011011010）
序列检测器：
检测一组或多组又二进制码组成的脉冲序列信号，当序列检测器连续收到一组或多组序列信号，如果与预先设置的码11010相同的时候，输出1，否则输出0.

整个系统分为两个模块：检测模块和解码模块。检测模块主要完成从输入串行序列判断出A，B或C信号，并分别输出脉冲标志脉冲串Signal_A，Signal_B和Signal_C；同时，当检测到任一信号时，BIT_EN_temp输出一个高脉冲。解码模块根据检测模块输出的三个标志脉冲进行0/1解码，输出最终的密勒解码数据DOUT；同时，输出DATA_EN和BIT_EN两个标志信号。-The whole system is divided into two modules: detection module

模拟雷达的探测威力（每一个距离库所能探测到的最小目标的dBZ）。
在此模拟中，分别模拟了雷达的频分脉冲的发射模式：窄波束补盲，宽波束主探测。同时也探究了波束在偏离法向一定角度、波束展宽下的探测威力(Analog radar detection power (dBZ of the smallest target that can be detected by each range library).
In this simulation, the transmission modes of the
