摘要/Abstract

摘要： 论述全向外辐射源雷达空中目标探测系统的主要问题及系统体制损失。针对单源单站（SISO）和单源三站（SITO）两种工作方式，在接收天线阵元数相同的情况下分析探测距离和定位精度。在单源三站条件下推导直角坐标系中的目标速度矢量表达式，并分析速度测量精度。研究结果表明，在一定条件下，单源三站组网方式的空间覆盖范围与单源单站相当，且具有平面定位精度较高，可获得目标速度矢量和技术实现难度小的特点。

Abstract: This work discusses the main problem and system loss in the aerial target detection system of omnidirectional passive radar. For the operation modes of radar system in SISO (single illumination and single observation) and in SITO (single illumination and triple observations), the detection ranges and measurement accuracies are analyzed under the condition that the numbers of array elements are the same. The target velocity expression is derived in SITO, and the accuracy of target velocity measurement is also discussed. The results show that SISO and SITO have about the same covering areas under certain conditions. Fortunately, SITO has the characteristics of high plane positioning accuracy, target velocity solvability, and low level of difficulty in technical implementation.

Key words: passive radar, target detection, SITO, detection range, location accuracy, velocity measurement accuracy
