干扰下的组网雷达目标跟踪分析

简述了组网雷达及其对抗技术概况,引入空间匀速直线运动与水平匀速圆周机动模型下状态方程与较强干扰强度下组网雷达的观测方程,运用扩展卡尔曼滤波,在干扰条件下实现对目标跟踪。通过对受到干扰与未受干扰状态下对目标跟踪仿真与误差对比,得出仅从压制干扰或距离欺骗干扰来对抗组网雷达,其效果是非常有限的。因此,对组网雷达的有效对抗还需综合考虑增加诸如角度欺骗干扰等其他手段协同实现。

Analysis of Target Tracking for Radar Network in Jamming

Radar network and ECCM of radar network is introduced.Using Extended Kalman Filter（EKF） applied on the system equation for model of spatial uniform velocity rectilinear movement ＆amp; horizontally regular circumferential movement and the measurement equation for radar network of different jamming level,target tracking of radar network will be realized in the presence of jamming.By the simulation of target tracking and comparison of their tracking error for the jammed radar network and no jammed radar network, the conclusion is obtained that jamming effect of ECM for radar network is very limited by using oppressive jamming and range-deceptive jamming. Therefore, the effective countermeasure of radar network needs cooperative jamming of integrated muhimode such as angle - deceptive jamming.
