摘要
针对从直扩信号直接提取角误差的单通道单脉冲体制提出了2种实现方法,并进行了理论分析,对系统处理过程中对角误差信号的影响因素进行了说明与计算分析;对信号处理过程中可能引入的随机窄脉冲干扰的产生机理进行说明,以及此窄脉冲干扰对角误差电压的影响进行了分析描述。利用MATLAB对此方案进行了数值仿真。仿真结果表明,从直接序列扩频信号中直接提取角误差的2种方法均是可行的,角误差电压的误差精度也较高。
The two SCM methods to obtain the angle error signal directly from the DS/SS signal are proposed in the paper.The theoretical analysis and mathematical derivation based on the two methods are made.The generating principle of the stochastic narrow pulse interference possibly introduced during the signal processing is discussed.The effect of the interference on the angle error is analyzed and described.The mathematic emulation is done by using MATLAB software.The results of the emulation prove that the two methods are not only feasible but also with higher precision.
