摘　　要：为了提高采用频扫天线的雷达系统在频扫维的测角能力,本文重点讨论了频扫单脉冲天线的实现技术,分析了三种不同实现方法,并以带状线形式、脊波导宽边缝隙形式和窄边波导缝隙形式为具体实现形式,设计了三种基于不同实现原理的频扫单脉冲天线实例,仿真及实测结果表明,三种实现方法都的有效性和正确性,可以应用于实际工程中。In order to improve angular measurement capability of radar system with frequency scan antenna,three implementation ways of frequency-scan monopulse antenna are specially discussed.Three frequency scan monopulse antenna examples based on three different implementation concepts are designed respectively by way of strip-line,ridge waveguide wide sidewall slots and narrow-edge waveguide slots.Simulation and measured results show that three implementation methods are all effective and correct,which can be applied in practical engineering.
