舰载相控阵雷达跟踪波束的计算机控制

Computer Control of the Tracking Beam within a Shipborne Phased Array Radar

在将多功能相控阵雷达应用于舰载环境时，提出了一个重要的问题，就是在舰船摇摆环境下，相控阵雷达电子波束如何稳定而且精密地指向目标。本文提出一种实现电子跟踪波束稳定的计算机控制方法──动态补偿舰船摇摆运动与自适应卡尔曼滤波相结合，计算机仿真结果表明，该方法能够使舰载相控阵雷达电子跟踪波束稳定而且精密地指向机动目标，并易于实现。

It is important for the electronic tracking beam within a phased array radar installed aboard to point to maneuvering targets stably and accurately.A new method is presented in order to realize computer control of electronic tracking beam stabilization. In this method, the real-time compensation algorithm is combined with the adaptive Kalman filtering and implemented in the computer. Computer simulation shows that the method and algorithm is suitable for electronic tracking beam aimming at maneuvering targets accurately on the condition of ship's motion (pitch and roll),and real-time implementation in a digital computer is feasible.
