摘　　要：比相单脉冲雷达采用和差通道接收信号比相的方法测角。一般认为 ,雷达事实上并不是在测量目标的方向 ,而是在测量目标的角闪烁方向。从特殊的两点目标出发 ,分析了单点目标和复杂目标下比相单脉冲雷达和差通道方式测角的原理与内在异同 ,探讨了比相单脉冲雷达测角与角闪烁的关系 ,提出有关雷达测角的新的观点。The phase comparison monopulse radar measures angles by comparing the phase of the difference channel signals with the phase of the sum channel signal. It has been generally accepted that what the radar measures is not the directions of the target, but angular glint errors. Starting with a special two point target here, this paper analyzes the principle of means of phase comparison monopulse radar used to measure the angles, discusses the internal relation between angle measurements of phase comparison monopulse radar and angular glints, and puts forward new viewpoints about radar angle measurements.
