摘要
单目标跟踪是机载PD雷达的一种重要的工作模式。从机载PD雷达的实际模型出发,对整个跟踪系统建立了比较准确和完整的仿真模型。仿真中距离门和速度门可以动态调整,角度跟踪采用四波束的比幅和差单脉冲,数据处理用卡尔曼滤波器实现对目标四维的动态跟踪。最后结合具体实例进行了系统仿真,结果表明可以获得比较高的稳态跟踪精度。
Single target tracking is an important operating mode of airborne pulsed Doppler radar. This paper sets up a relatively exact gate and velocity gate can be simulation model for the tracking system based on the actual model. The range adapted dynamically. Four-beam amplitude comparison monopulse is used for angle tracking. Kalman filter is used for the data processing as a four-dimensional tracking filter. The resuits of the simulation by specific situation illuminate that the tracking precision satisfies the tracking need.
