摘　　要：分析了基于自相关的激光编码解算方法在多路激光威胁信号的周期解算中准确度和适应性差的问题,引入了加权归一系数,对原来的算法进行了改进。通过matlab的仿真实验,证明该方法可以在短时间内准确地完成混合信号周期解算。The conventional auto correlation methodology is not ideal in decoding the period of threatening laser source when disturbing or omitted pulses exist. A novel normalized weighting arithemetic was introduced to solve the problem. The deduction of the new method was illustrated and simnlation was made. The simulation results show good cornform ability with the analysis conclusion.
