摘　　要：在复杂电磁环境中对威胁目标进行精确测向定位尤为重要,目前主要依靠高精度雷达和测向接收机2种方式。测向接收机具有探测距离更远的优势,且能进行信号识别,通常采用干涉仪测向、数字波束形成(DBF)测向、比幅测向、时差测向定位等体制。针对各类型接收机设计了一种高精度大动态验证系统,基于动态对抗场景规划想定,按照场景中我方与目标的相对位置关系、目标信号参数、天线扫描特性等动态推演解算,驱动多台通用仪器生成多路幅相相参的射频信号,直接注入被测接收机,接收机解算多路带幅相关系的信号后对目标进行测向,再将测向结果与场景中的准确位置关系进行比较,从而评估接收机的测向性能。该系统硬件部分采用通用仪器,具有高精度、大动态、高可靠性、可灵活重构等诸多优点。It is important to perform accurate direction finding(DF)and positioning to the threat targets in complex electromagnetic environment,which mainly depends on two modes of high-precision radar and DF receiver at present.DF receiver has the advantages of longer detection distance and signal identification,conventionally uses the system of interferometer DF,digital beam forming(DBF)DF,amplitude comparison DF,time difference of arrival(TDOA)DF and positioning.This paper designs a high-precision and large-dynamic verification system for multi-type DF receivers,which is based on dynamic confrontation scenario planning,deduces and calculates the dynamic state according to the relative position relationship between the enemy target and our receiver,target signal parameters,antenna scanning characteristics,etc.in the scene.Several common devices are driven to generate multi-channel amplitude and phase coherent radio frequency(RF)signals,and the signals are injected into the measured receiver,then the receiver performs DF to the target after solving multi-channel signals with amplitude-phase relationship.The result is compared with accurate position in the scene,thereby the DF performance of receiver is evaluated.Conventional devices are adopted in the system hardware,which has advantages of high precision,large dynamic,high reliability,flexible reconstruction and so on.
