| 摘 要： | 根据MTD雷达特点,设计了基于中频采样、可用于MTD雷达的自适应定频实现方法。该方法通过频谱分析,找出了宽带干扰频谱的凹点和凹区,然后控制雷达以最佳或准最佳的频率工作,达到抗广谱有源干扰的目的。描述了自适应定频基本原理,详细介绍了数据采集、频谱分析、频点选择和信息流程。该方法利用自身电路特点实现了自适应定频,不需要增加设备硬件,也不浪费时间资源,方法简单、实用。试验结果验证了设计的有效性。

| Abstract: | According to the characteritics of MTD radar,a method to realize the self-adaptive fixed-frequency used for MTD radar based on the intermediate-frequency sampling was designed.The pit and concavity in wide-band disturbance frequency spectrum is found out with the method by spectrum analysis,and then the radar is controlled to work at optimal or quasi-optimal frequency to realize anti-interference.The basic principle of the self-adaptive fixed-frequency is described.The data acquisition,spectrum analysis,fre... |
