  • 摘要: 該文針對(duì)單調(diào)頻廣播外輻射源雷達(dá)面臨的帶寬時(shí)變及RCS閃爍等問(wèn)題，研究了多調(diào)頻信號(hào)聯(lián)合探測(cè)的實(shí)驗(yàn)方案，并利用武漢大學(xué)研制的多調(diào)頻外輻射源雷達(dá)系統(tǒng)開(kāi)展了外場(chǎng)實(shí)驗(yàn)驗(yàn)證。首先，闡述了多調(diào)頻廣播外輻射源雷達(dá)的工作原理。然后，分析了多調(diào)頻廣播信號(hào)特性，論證了利用多調(diào)頻信號(hào)聯(lián)合探測(cè)的必要性和優(yōu)越性。最后，重點(diǎn)展示了實(shí)測(cè)數(shù)據(jù)的處理結(jié)果。研究表明：多調(diào)頻探測(cè)方案能大幅提高目標(biāo)檢測(cè)概率，提升調(diào)頻外輻射源雷達(dá)探測(cè)穩(wěn)健性，外場(chǎng)實(shí)驗(yàn)驗(yàn)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.
