雷达自适应频率控制系统干扰检测研究与实现

摘要

Adaptive frequency radar controlling system is an important way against active suppressing jamming. The de signs of system, jamming detect arithmetic, how to select the optimization frequency point and the jamming detect circuit is introduced in this paper. The controller used MCU and 74LS161 as the core. It finds the frequency points which have the least jamming by signal detection and estimation theory and frequency spectrum analysis. The MCU controls the transmitter to work in these frequency points for anti-jamming.%雷达自适应频率控制系统是针对有源压制性干扰的重要抗干扰措施.对该系统的总体设计、干扰检测算法、最优频率点选择和干扰检测电路等系统组成的关键技术进行介绍.该控制器以单片机和74LS161芯片为核心,综合运用信号检测与估计理论,通过频谱分析找出干扰最小的频点,然后控制发射机以该频点进行工作,达到有效对抗干扰的目的.
