  • 摘要: 認(rèn)知雷達(dá)可以在探測過程中不斷優(yōu)化自身系統(tǒng)參數(shù),實(shí)現(xiàn)與當(dāng)前探測環(huán)境的匹配,從而能夠改善雷達(dá)的探測性能。針對(duì)未知目標(biāo)的探測問題,利用當(dāng)前回波數(shù)據(jù)更新目標(biāo)分量的估計(jì)值及其協(xié)方差矩陣,基于目標(biāo)相關(guān)信息優(yōu)化下一次探測所需的發(fā)射機(jī)波形和接收機(jī)濾波器,并構(gòu)成一個(gè)閉環(huán)處理過程。該文提出了兩種優(yōu)化途徑,第1種途徑利用目標(biāo)分量的估計(jì)僅優(yōu)化下一次探測波形,在接收端采用廣義匹配濾波器;第2種途徑將估計(jì)誤差等效為信號(hào)依賴的噪聲,聯(lián)合優(yōu)化發(fā)射波形與接收機(jī)濾波器。計(jì)算機(jī)仿真分析表明,采用閉環(huán)迭代優(yōu)化的方法是漸進(jìn)等效的,并可以在相干累積獲得的性能增益基礎(chǔ)上,進(jìn)一步改善雷達(dá)的探測性能。
