摘要
针对跟踪雷达的航迹干扰问题,提出一种基于多相位分段调制处理的跟踪雷达航迹干扰方法。对该方法的基本原理进行说明,建立干扰信号的数学模型,以无迹卡尔曼滤波（UKF）为例,在距离域和多普勒域对多相位分段调制干扰产生的UKF航迹跟踪误差进行了推导,分析了信号分路数、调制相位数2个干扰参数对航迹跟踪误差的影响。通过仿真验证相关干扰效果,表明该方法能够改善传统干扰方法在多普勒域的局限性,在距离域和多普勒域对跟踪雷达形成灵活多样的航迹干扰效果。
Aiming at track-jamming for tracker radar,ajamming method based on multiple phase sectionalized modulation is proposed to tracker radar.Its basic principle is illustrated,and the jamming signal＇s mathematical model is established.Unscented kalman filter（UKF）is raised as an example to derive UKF track tracking error generated by multiple phase sectionalized modulation jamming,and the impacts on track tracking error by number of signal shunts,and phase modulation value are analyzed.Simulation is conducted to prove the related jamming effects,it is flexible and diverse to generate different jamming effects in range domain and doppler domain by applying this method,the limitation of the traditional jamming method in doppler domain can be improved.
