摘　　要：针对电子战中对目标无源快速定位需求,基于干涉仪测向系统,推导了利用角度测量和最小二乘估计的定位算法,通过相位和相位差变化率测量结合卡尔曼滤波的定位算法。在实现复杂度、适用范围、定位精度、收敛速度等方面对算法进行比较,结果表明,第二种定位算法由于利用了更多信息并采用了跟踪滤波算法,定位精度更高、收敛速度更快,同时算法采用递归结构,具有运算简单、高效的特点,能够实时适应载机速度、航向等参数状态变化,具有较高的军事工程应用价值。According to passive location of fix communication station by single airborne,based on phase interferometer system,a location algorithm using direction measurement and least-square estimation,and a location algorithm using phase and phase difference rate of change measurement combined with Kalman filtering are derived.The algorithms are compared in terms of implementation complexity,scope of application,location accuracy,and convergence speed.Experimental results indicate that the second location algorithm has higher location accuracy and faster convergence speed due to the use of more information and the use of tracking filtering algorithms.At the same time,the algorithm adopts a recursive structure,which has the characteristics of simple operation and high efficiency,and can adapt to the changes of parameters such as the speed and heading of the aircraft in real time,and has high military engineering application value.
