3、線和2個(gè)0.5m天線,大大降低了系統(tǒng)對(duì)標(biāo)校站的建設(shè)要求。當(dāng)相控陣天線波束合成損失大于ldB,系統(tǒng)可采用單站粗略標(biāo)校+三站精確標(biāo)校的改進(jìn)算法進(jìn)行天線標(biāo)校;當(dāng)相控陣天線波束合成損失在1dB以內(nèi),系統(tǒng)可省略單站粗略標(biāo)校過(guò)程直接進(jìn)行三站精確標(biāo)校。關(guān)鍵詞:相控陣天線;在軌標(biāo)校;旋轉(zhuǎn)矢量(REV);粗略標(biāo)校;精確標(biāo)校中圖分類號(hào):V556.6;TN820.1’2文獻(xiàn)標(biāo)志碼:A文章編號(hào):16745620(2016)03—0175一06IN)I:10.7642/j.issn.1674—5620.2016—03—0175一06Calibra
