基于数字电视广播信号的无源雷达实验研究
Experimental Results of Dual-polarization Passive Radar Based onDigital Television Broadcasting Signal
摘要
Abstract
The spatial filtering and dual-polarized channel cancellation method are proposed for the clutter suppression in the passive radar.A multichannel wideband receiving and processing system is designed, and the digital television terrestrial broadcasting (DTTB) signal is chosen to carry out civil aircraft target detection experiment.The polarization and spatial filtering methods are used to solve the strong direct path interference suppression problems incurred by the receiving system location;combined with the characteristics of the DTTB signal, the block length selection interval in the block batch processing method for range-Doppler image calculation is given.The clutter cancellation performance of different polarization channels are analysed through the experimental data, and the results show that the proposed method in the passive radar experiment can improve detection performance of the passive radar.关键词
