摘要
介绍了一种用于雷达模拟器的天线系统设计,该系统采用角锥喇叭天线组成比幅测角系统,解决了方位波束宽度大和天线增益高之间的矛盾,具有结构简单、易于实现、天线增益和测角精度高等特点。经测角误差分析和电磁仿真,证明天线系统的增益系数、测角范围和测角精度等主要技术指标满足雷达模拟器设计要求,具有推广应用价值。
In this paper, the antenna system designed for radar simulator was described. The system used horn antennas to constitute amplitude ratio angle measuring system, to solve the contradiction between azimuth beam width and antenna gain. It had a simple structure, ease of implementation, high antenna gain and high precision in angle measurement. By measuring angle error analysis and electromagnetic simulations, it was proved that main technical indicators such as gain coefficient, measuring angle range and angle measurement precision of antenna system met the design requirements of radar simulator, therefore, it had application value.
