摘要

摘要: 該文針對單調(diào)頻廣播外輻射源雷達面臨的帶寬時變及RCS閃爍等問題，研究了多調(diào)頻信號聯(lián)合探測的實驗方案，并利用武漢大學(xué)研制的多調(diào)頻外輻射源雷達系統(tǒng)開展了外場實驗驗證。首先，闡述了多調(diào)頻廣播外輻射源雷達的工作原理。然后，分析了多調(diào)頻廣播信號特性，論證了利用多調(diào)頻信號聯(lián)合探測的必要性和優(yōu)越性。最后，重點展示了實測數(shù)據(jù)的處理結(jié)果。研究表明：多調(diào)頻探測方案能大幅提高目標檢測概率，提升調(diào)頻外輻射源雷達探測穩(wěn)健性，外場實驗驗證了該方案的可行性。

Abstract: FM based passive radar faces some issues such as time varying bandwidth and RCS glint, a multiple FM joint detection scheme is proposed, and the corresponding experiments with passive radar system developed by Wuhan University are carried out. First, the process flow of multi-FM based Passive Radar is introduced. Then, the signal characteristics of multi-FM for radar application are analyzed, meanwhile, the necessity and advantages of multi-FM scheme are demonstrated. Finally, the practical processing results are presented. Experiment result proves that multiple frequency detection scheme can substantially improve target detection performance, enhanceing the robustness of passive radar system.
