摘　　要：针对实施压制性干扰的电子干扰飞机,提出了雷达网对其进行测向定位与跟踪的方法。首先,比较了压制性和欺骗性2类电子干扰的实现原理,分析了两者在作战使用中优缺点,提出了对实施压制性干扰的电子干扰飞机进行测向跟踪的需求;接着,根据多种情况下测向交叉定位的定位误差分析,给出了测向站布阵最优方法;然后,分析了影响测向交叉定位的各种不利因素,提出了精确计算定位点和滤波跟踪方法,辅助时差测距方法估计干扰源高度,并结合实际应用场景提供了虚警抑制的多种技术途径;最后,通过仿真分析表明该方法的定位跟踪效果。Aimed at the electronic jamming aircraft performing blanket jamming,a method for direction finding,location and tracking in the radar net is proposed.Firstly,the realization mechanisms of the blanket jamming and the deception jamming are compared.Their advantages and the disadvantages are analyzed in operational use.The direction and location requirements to the electronic jamming aircraft performing blanket jamming are presented.Secondly,according to the location error analysis of the direction cross location under various conditions,the optimizing method for the direction finding station position is proposed.Then,the disadvantages of the direction cross location are analyzed.A location calculating and filter tracking method is presented.The height of the jamming source is estimated with the time difference ranging method,and the various technique approaches of the false alarm suppression are provided combined with the actual application scene.Finally,the simulation analysis shows the location tracking effect of the method.
