MIMO Radar Orthogonal Waveform Set Design Based on Chirp Durations

  • 摘要: 線(xiàn)性調(diào)頻(LFM)信號(hào)是一種被廣泛應(yīng)用的大時(shí)寬帶寬積信號(hào),利用LFM信號(hào)的多樣性可設(shè)計(jì)多輸入多輸出(MIMO)雷達(dá)的正交波形。該文針對(duì)現(xiàn)有波形相關(guān)函數(shù)存在的問(wèn)題,以理論分析為基礎(chǔ),提出一種基于LFM時(shí)寬的發(fā)射波形,并給出了一種相應(yīng)的正交波形設(shè)計(jì)方法。該方法以峰值旁瓣電平為準(zhǔn)則,利用序列二次規(guī)劃對(duì)各子脈沖LFM信號(hào)的時(shí)寬進(jìn)行優(yōu)化設(shè)計(jì)。仿真結(jié)果表明,與現(xiàn)有方法相比,所設(shè)計(jì)波形具有較低的自相關(guān)旁瓣電平和互相關(guān)電平。此外,通過(guò)數(shù)值實(shí)驗(yàn)分析了相關(guān)性能隨波形個(gè)數(shù)及子脈沖個(gè)數(shù)的變化關(guān)系。
