单脉冲跟踪雷达抗双点源干扰研究

Study on Monopulse Tracking Radar Against Counter Double-Point Sources Jamming

角度自动跟踪系统是跟踪雷达的最主要、最基本的系统,单脉冲角跟踪系统是目前最为先进的角度自动跟踪系统,但其较容易受到双(多)点源的干扰,为提高单脉冲雷达的抗干扰能力,本文根据其测角原理,分别计算出雷达受干扰时的大、小功率干扰源的偏离角,提出采用选择性的跟踪双点源干扰中的大功率源或小功率源的方法进行抗干扰。

Automatic angular tracking system is the most essential and important system in a tracking radar; and monopulse angular tracking system is the most advanced angular tracking system up to now, while it is vulnerable by double （ or multiple ） points source jamming. In order to improve anti-jamming capability of the monopulse tracking radar, according to angular measurement principle, an anti-jamming method by selectively tracking high power source or low power source is proposed based on computed offset angles of high and low power jamming sources when the radar is jammed.
