【摘要】：介紹了具備方位向大掃描角能力的高分辨率機(jī)載合成孔徑雷達(dá)(SAR)系統(tǒng),重點(diǎn)研究了綜合電子設(shè)備技術(shù),包括寬帶信號(hào)產(chǎn)生、多子頻帶接收、寬帶脈沖信號(hào)初相高穩(wěn)定度技術(shù)等,并對(duì)不同子帶的相位幅度特性以及脈沖壓縮特性進(jìn)行了分析。機(jī)載飛行試驗(yàn)及成像處理得到的高質(zhì)量SAR圖像,驗(yàn)證了寬帶發(fā)射多子帶接收的綜合電子設(shè)備設(shè)計(jì)技術(shù)和技術(shù)性能。
[Abstract]:A high resolution airborne synthetic aperture radar (SAR) system with large azimuth scanning angle is introduced, and the integrated electronic equipment technology, including wideband signal generation and multi-subband reception, is studied emphatically. The phase amplitude characteristics and pulse compression characteristics of different sub-bands are analyzed. The high quality SAR images obtained from the airborne flight test and imaging processing verify the design technology and technical performance of the integrated electronic equipment for broadband transmission and multi-subband reception.
