Abstract

Integrated efficiency factors are used not only at the design stage, but also in the case of choosing a ready-made system. In this case, the purpose of the research is to get an answer to the question of the expediency of its purchase (deployment), or monitoring the effectiveness of the system during its operation and developing proposals for optimizing the ways of its use and modernization. Since any system has limited resources when solving assignment tasks, it is necessary to develop a generalized efficiency factor from the standpoint of analyzing the effective allocation of radar resources when using antenna systems of various types in its composition. The aim of the article is to increase the efficiency of the use of radar resources in the antenna system. Achieving this goal includes solving the following tasks: substantiation of an integrated efficiency factor of the use of the antenna system in the radar, the use of an integrated efficiency factor to compare different types of antenna systems in the radar. А comparison of the efficiency of using a digital antenna array (DAA) with two-dimensional electronic scanning of the radiation pattern and parallel space surveillance, a reflector antenna, a passive phased antenna array with one-dimensional scanning, as well as an active phased antenna array with one-dimensional scanning and parallel space surveillance has been performed. It has been shown that the efficiency of using a DAR with two-dimensional electronic scanning is 2.3...15.6 times higher than the efficiency of other types of antenna systems. The proposed efficiency factor makes it possible to compare the efficiency of the use of radar resources when using different types of antenna systems, taking into account the features of their construction and the requirements for the purpose of the radar.
雷达中天线系统的综合效率系数
综合效率因素不仅在设计阶段使用,而且在选择现成系统的情况下也使用。在这种情况下,研究的目的是得到其购买(部署)的便利性问题的答案,或者在其运行期间监测系统的有效性,并提出优化其使用和现代化方式的建议。由于任何系统在解决分配任务时资源都是有限的,因此从分析其组成中使用各种类型的天线系统时雷达资源的有效分配的角度出发,有必要建立一个广义的效率因子。本文旨在提高天线系统中雷达资源的利用效率。实现这一目标包括解决以下任务:证实在雷达中使用天线系统的综合效率因子,使用综合效率因子来比较雷达中不同类型的天线系统。А对具有二维电子扫描辐射方向图并行空间监视功能的数字天线阵列(DAA)、具有一维扫描功能的反射天线、无源相控阵以及具有一维扫描功能并行空间监视功能的有源相控阵的效率进行了比较。研究表明,采用二维电子扫描雷达的效率是其他天线系统效率的2.3 ~ 15.6倍。所提议的效率系数使人们能够在使用不同类型的天线系统时比较雷达资源的使用效率,同时考虑到它们的结构特点和雷达用途的要求。
