相控阵雷达搜索参数研究

通过对相控阵雷达搜索参数研究,从概念和系统的角度,提出了监视空域与预警时间、搜索时间与搜索帧周期、跟踪数据率、波位编排方式、确认时间、跟踪容量等参数的选择原则和确定方法;分析了天线的扫描角增益损失,给出了相应的能量补偿办法;建立了确认概率、起始跟踪距离的概念,按照信噪比与确认概率、积累检测概率的关系将雷达对目标的发现过程划分为4个阶段。

A Study on Search Parameters in Phased Array Radar

The search parameters of phased array radar are studied from the point of view of concept and system.The se- lection principle and method for a number of search parameters are presented,including surveillance space,warning time,search time,search frame period,tracking data rate,beam-position arrangement,validating time and tracking capacity.The gain reduc- tion caused by the scanning angle of antenna is analyzed and the corresponding energy compensation method is presented.The con- cepts of validating probability and tracking Initiation distance are introduced.According to the relation between signal-noise ratio and validating probability,the procedure of detection is divided into four phases.
