| 摘 要： | 提出一种新的频率引导设计方法。该方法将成熟的数字射频存储器作为可受控的射频跟随器,利用其所具有的极小的读写间隔时间特点,使系统的置频时间控制在很短范围之内,以解决系统完成频率引导功能时工作灵敏度、瞬时工作带宽及系统响应时间三者之间的矛盾,从而能在复杂的电磁环境中保持对窄脉宽、脉间大范围跳变等雷达信号的侦察和跟踪。

| Abstract: | A new solution for frequency directing is presented.The mature DRFM is used as controllable RF follower.Its advantage of very short read-write cycle allows the frequency presetting within a very short period of time,providing a tradeoff among sensitivity,instantaneous bandwidth and response time in the system.The proposed solution can ensure the system to detect and track the radar signals with narrow pulse-width and big pulse-to-pulse frequency hopping range in complex electromagnetic environment. |
