中文说明： GPS和INS组合导航程序，ldpc码的编解码实现，DC-DC部分采用定功率单环控制，FMCW调频连续波雷达的测距测角，从先验概率中采样，计算权重，自己编的5种调制信号。
English Description：
GPS and INS navigation procedures, encoding and decoding of LDPC codes implemented DC-DC using fixed-power single-loop control, FMCW ranging angular frequency modulated continuous wave radar, sampled from the prior probability, calculating weight, made up of 5 kinds of modulation signal.
