| 摘 要： | 在同轴跟踪雷达系统中，前馈是为了克服伺服系统的二阶动态滞后而采取的一项关键技术。文中结合同轴跟踪系统模型，将前馈引入计算机数据处理部分，提出一种自适应前馈方法，并结合专门开发的同轴跟踪系统仿真软件，对前馈参数的选取进行了讨论。最后与无前馈的传统单脉冲雷达的仿真跟踪试验进行对比，验证了其自适应前馈的效果。

| Abstract: | The feedforward is one of key methods to reduce the dynamic lag in on-axis tracking radar system. A new self-adaptive feedforward model is proposed as a module of the computer data processing in this paper. Based on the simulation soft-ware, many data are obtained and the method of how to select the parameters for feedforward is discussed. Finally, by simulated comparison with mono-pulse radar system without feedforward, it is shown that the self-adaptive feedforward can significantly improve the tracking accuracy and performance. |
