【摘要】：介绍了一种无源定位机场场面监视雷达时差接收机,该接收机采用了微波光电技术。微波光子学是一项被认为为未来高性能雷达、电子战系统提供一种非常具有吸引力的新技术领域,具有更远的传输距离和更大的带宽。目标微波信号通过多子站接收、传输至中心站进行幅度检测和时间测量,接收子站简单便捷、布站灵活,同时解决了多站时间同步问题,结合波分复用时间校准,实现高精度时差测量。目前该接收机已完成样机研制和应用试验,定位精度明显优于传统时差接收机,文中给出了实验数据和研制结果。
[Abstract]:A time difference receiver for passive airport scene surveillance radar is introduced. The receiver adopts microwave photoelectricity technology. Microwave photonics is considered to be an attractive new technology field for future high-performance radar electronic warfare systems with longer transmission distance and wider bandwidth. The target microwave signal is received by multiple substations and transmitted to the central station for amplitude detection and time measurement. The receiving sub-station is simple and convenient, and the distribution of the station is flexible. At the same time, the problem of multi-station time synchronization is solved, and the time calibration is combined with wavelength division multiplexing. High precision time difference measurement is realized. At present, this receiver has completed the prototype development and application test, and the positioning accuracy is obviously better than that of the traditional time difference receiver. The experimental data and the development results are given in this paper.
