| 摘 要： | 文章推导了非相干两点源作用下干涉仪导引头测角输出的期望和方差。理论研究表明,两点源信号幅度不相等时,脉冲积累后的导引头输出指向大功率源。文章还推导了导引头输出方差一定时需要的最少脉冲积累数,和对辐射源脉冲重复频率的要求。仿真实验验证了文章得到的结论。

| Abstract: | In this paper we analyzed the expectation and variance of interferometer seeker's output, which in the condition of noncoherent dual sources system. Theoretic study shows that the seeker points to the bigger power source via pulse accumulation when the dual sources have different amplitude. In this paper we also analyzed the needed least pulse accumulation number and the demand to pulse-repeat-frequency of emitter when the variance of the seeker's output is confirmed. Simulation results demonstrate the theoretic analysis result. |
