摘要
针对传统的电域测向方法工作频率低、带宽窄,很难满足未来电子侦察系统需求的难题,介绍了一种结构紧凑的基于相位干涉仪原理的微波光子测向方案,利用双平行马赫曾德调制器来实现超宽频带的高精度测向。仿真和实验结果表明,所提出的设计方法可以在5~40 GHz频率范围内实现-90°~+90°的相位差测量,测量相位误差可达到±2°以内。
Aiming at solving the problem that the traditional electrical direction finding technology cannot meet the requirements of future electronic reconnaissance systems,a microwave photonic direction finding compact system based on phase interferometer principle is proposed and studied by simulation in this paper,using the double parallel Mach-Zehnder(DP-MZM)modulator to realize direction finding with ultra-wide band and high accuracy.The simulation and experiment results show that the proposed system can achieve the phase difference measurement from-90°to 90°in the frequency range of 5~40 GHz,and the measuring error is within±2°.
