本文主要讨论在高频实现三路合一的假单脉冲雷达体制,力图从理论与实践的结合上阐明它的工作原理、收发方向图和宽频带特性,并在比较三种方案的基础上,肯定了采用铁氧体调制器和可变耦合器的优越性,最后论述了这种体制在火控雷达抗角欺骗干扰、脉冲多卜勒角跟踪及消除波束滚动等三个方面的应用。 In this paper, we mainly discuss the three-way pseudo-monopulse radar system at high frequency, trying hard to clarify its working principle, transmitting and receiving direction diagram and broadband characteristics from the combination of theory and practice. Based on the comparison of three schemes, The advantages of using ferrite modulators and variable couplers are affirmed. Finally, the application of this kind of system in three aspects of anti-jamming, pulse Doppler tracking and beam roll elimination are described.
