摘要
相位差变化率含有目标辐射源的距离信息,是机载单站无源定位系统中的重要参数。讨论了单站无源定位中相位差变化率测量的问题,介绍了差分法、线性拟合法和卡尔曼滤波法的测量原理。在理论分析的基础上,通过计算机仿真分析了几种测量方法的性能及优缺点,并验证了这些算法的正确性和有效性。
As an important parameter in the single airborne passive locating system, the rate of phase difference change contains range information of radio emitter. Illustrates the principle of passive location through measurement of rates of phase difference change, the measurement principles of difference, linear curve fitting and Kalman filtering are introduced. Based on theory analysis, performances of these algorithms are thoroughly analyzed according to simulation results.
