【摘要】：無(wú)論是軍用還是民用領(lǐng)域,雷達(dá)技術(shù)都是探測(cè)遠(yuǎn)程目標(biāo)的常用技術(shù)之一。雖然各種雷達(dá)技術(shù)日益成熟,但在接收目標(biāo)回波信號(hào)時(shí),還是不可避免地會(huì)受到各類(lèi)散射物體產(chǎn)生的干擾雜波信號(hào),最常見(jiàn)的就是云、雨、復(fù)雜地形帶來(lái)的信號(hào)干擾,影響雷達(dá)對(duì)目標(biāo)的探測(cè)能力。本文是基于ADS軟件建立雷達(dá)信號(hào)目標(biāo)檢測(cè)系統(tǒng),根據(jù)相位編碼信號(hào)和目標(biāo)回波信號(hào)準(zhǔn)確計(jì)算出距離,并同步跟蹤目標(biāo)方位角,得到目標(biāo)在天線(xiàn)掃描圖中的位置,而且很好地抑制雷達(dá)雜波干擾,提高了雷達(dá)探測(cè)精度。
[Abstract]:Radar technology is one of the commonly used techniques to detect long-range targets in both military and civil fields. Although various radar technologies are becoming more and more mature, when receiving the target echo signal, it is inevitable that it will be interfered by various kinds of scattering objects, the most common is the cloud, rain, complex terrain signal interference. The ability of radar to detect targets is affected. In this paper, the radar signal target detection system is established based on ADS software. The distance is calculated accurately according to the phase coded signal and the target echo signal, and the target azimuth angle is tracked synchronously, and the position of the target in the antenna scan map is obtained. Moreover, the radar clutter interference is suppressed well and the radar detection accuracy is improved.
