由于单脉冲导引头由一个雷达脉冲就能完全准确地得到角跟踪信息,所以很容易被认为是最好的射频测量装置。本文简要地指导性地描述了各种普通的单脉冲导引头,它们可以归纳为三大类:相位比较导引头、幅度比较导引头和双模螺旋导引头。虽然有很多可参阅的文献描述了这些导引头,但本文把所有的信号处理方法综合成一篇报告,并将数学模型加以推广以包括多射频源的影响。多源问题近几年来在存在多路径和(或)多目标情况下的雷达和导引头系统分析中,已日益变得重要。本文还提供了每一种导引头在两源和三源环境中的响应特性与射频源的相对功率和相位的函数关系,它们是用计算机模拟获得的。最后,根据这些结果,对某些感兴趣的重要的响应特性作了比较。
Since a single pulse seeker can obtain angular tracking information with complete accuracy from a single radar pulse, it is easily considered as the best RF measurement device. This article provides a brief overview of a variety of common single-pulse seeks that can be grouped into three broad categories: phase comparison seeders, amplitude comparison seekers, and dual-mode seeders. Although many see references describe these seekers, this article synthesizes all signal processing methods into a single report and extends the mathematical model to include the effects of multiple RF sources. Multi-source problems In recent years the analysis of radar and seeker systems in the presence of multiple paths and / or multiple targets has become increasingly important. This article also provides a functional relationship of the response characteristics of each seeker in two- and three-source environments with respect to the relative power and phase of the RF source. These are obtained using computer simulations. Finally, based on these results, some of the important response characteristics of interest are compared.
