在现代雷达中广泛运用单脉冲枝术来精确测量目标的角座标(方位和仰角)。本文首先在单一脉冲基础上分析各种不同形式的脉冲处理器,再得出以各种不同参数为函数的热噪声对角精度的影响。然后研究关于一些不同的检波后算法对相同驻留时间内目标回波的有效处理问题,特别研究这些算法在三座标单脉冲雷达中的应用,而对其它单脉冲系统也是适用的。也讨论了对同一目标可同时测量的优点,当然这是对用在三座标雷达的俯仰角扫描和全相控阵雷达来说的。
The monopulse technique is widely used in modern radars to accurately measure the angular coordinates (azimuth and elevation) of a target. In this paper, we first analyze different types of pulse processors on the basis of a single pulse and then obtain the influence of the thermal noise diagonal accuracy as a function of various parameters. Then, some different post-detection algorithms are studied to deal effectively with the target echoes in the same dwell time. In particular, the applications of these algorithms in the three-coordinate monopulse radar are studied, and are also applicable to other single-pulse systems. It also discusses the advantages of being able to measure simultaneously on the same target, of course, for pitch-panning and phased-array radars used in radars.
