【摘要】：以臨近空間高超聲速目標(biāo)防御為背景,研究了無引導(dǎo)信息下遠(yuǎn)程預(yù)警相控陣?yán)走_(dá)搜索能力問題。針對臨近空間工作模式,深入分析了雷達(dá)搜索屏、脈沖寬度、信號周期、搜索幀周期等搜索參數(shù)的設(shè)計(jì)原則和確認(rèn)方法,分析了脈沖寬度隨波束指向變化補(bǔ)償關(guān)系,推導(dǎo)了目標(biāo)不同高度仰角穿屏的最短穿屏距離和雷達(dá)捕獲目標(biāo)的最小掃描次數(shù),以HTV-2為例仿真分析了雷達(dá)的探測能力,結(jié)果表明當(dāng)目標(biāo)迎面來襲時(shí)雷達(dá)具備完全的捕獲能力,當(dāng)目標(biāo)從后方頂空來襲時(shí)為捕獲目標(biāo)需要采取TWS模式。
[Abstract]:Based on the hypersonic target defense in near space, the search ability of remote early warning phased array radar without guidance information is studied. The radar search screen, pulse width and signal period are deeply analyzed for the near space operation mode. The design principle and confirmation method of searching parameters such as frame period are analyzed. The compensation relationship between pulse width and beam direction is analyzed. The shortest penetration distance of target at different elevation angles and the minimum scanning times of radar capture target are deduced. Taking HTV-2 as an example, the detection ability of radar is simulated and analyzed. The results show that the radar has complete capture capability when the target is coming head-on, and the TWS mode is needed to capture the target when the target is coming from the rear headspace.
