摘　　要：介绍了圆锥扫描红外导引头幅值信号提取和时间信号提取的两种方法。分析了基准信号相位发生误差的原因 ,并给出了相位误差的分布情况。在此基础上比较了两种不同信号提取方法的优缺点。提出了利用信号产生器产生基准信号 ,用于解决幅值信号提取法遇到的相位误差问题。Two ways of getting signal from Circular-cone scan infrared homing head are given, one is getting signal form range another is getting from time. The reasons to the error of phase of postulate signal are analyzed and the distribution of the drift of phase is given. From the comparison on two ways of getting signal, goodness and badness of the two ways are given.
