反辐射导弹的最优检测

Optimum Detection for Anti Radiation Missile

本文以反辐射导弹告警系统为背景，根据典型反辐射导弹的发射模式，建立了反辐射导弹雷达回波时间序列模型，指出告警系统对反辐射导弹的脉冲串检测实际上是速度及加速度分量未知的线性调频信号的检测。推导了反辐射导弹的最优检测的表达式及参数估计的精度，并给出了最优检测的检测性能，为工程完成反辐射导弹回波脉冲串的检测提供了理论基础。

In this paper, based on the alarm system of anti radiation missile and the launch pattern of anti radiation missile,time series models of anti radiation missile are bulit. And it is pointed out that the detection of pulse series finished by the alarm system is actually the detection of Linear Frequency Modulation with unknown velocity and acceleration components. The paper presents the equation of optimum detection for anti radiation missile and precision of its parameter estimation, and the detection performance is also given.All these analysis offer the theorectical basis for the detection of anti radiation missile.
