[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.
