雷达动态多目标模拟系统的设计

Design of a dynamic multi-target simulating system for radar

雷达动态多目标模拟系统旨在解决如何检测相控阵测量雷达的多目标跟踪性能这一技术难题。系统采用程控延时技术、数字控制技术及中断处理技术,可模拟10个以上运动目标,目标距离不受雷达重复频率的限制;采用数字存贮技术对地物杂波信号进行模拟,杂波分布可随场地和天线波束指向变化;对多台雷达同时工作时的同频干扰信号进行了模拟。系统可选择高频和视频两种接口将目标信号输入雷达,以适应各种检测要求。该系统可以有效检测相控阵雷达多目标跟踪性能,同时为雷达操作人员提供了实用的模拟训练器材。

The Dynamic Multi-object Emulator（DMOE） can solve the problem how to evaluate multi-object tracking capabihty of the Phased-Array Radar（PAR）. Many advanced technologies are applied in DMOE such as program-controlled time-lag technology, digital control technology and interrupt service technology and so on. It can emulate more than 10 moving objects. Position of each object is free of radar＇ s repeating-frequency. Noise signals are also emulated through digital storage technology. The distribution of noise signal varies with the change of landform and the antenna beam direction. The interfering signal with the same frequency when several radars works at the same time are also emulated. Two interfaces of high-frequency and video can be selected by the system for inputting target signal into the radar, therefore it can be used for different tasks of evaluation. The emulator can evaluate multi-object tracking capabihty of PAR, it is also helpful for radar operator training.
