【正文】 highclass information of position, speed and time in despite of weather. Due to the weak power of arriving GPS signal and plicated electromagnetic interfere in propagation channel, effective measures must be taken to eliminate interference signals in order to advance the GPS receiver39。s easy to be interfered. Therefore, anti–jamming play a key role in satellite navigation system. Among so many anti jamming technologies,adaptive zero antenna is the best anti–jamming performance. In this paper, the adaptive antiinterference antenna zero of the adaptive algorithm is pared, and deduced thepower inversion arithmetic, and the adaptive antiinterference antenna zero antijamming performance Key words:GPSAnti–jammingAdaptive zero antenna Power inversion arithmetic5PCzVD7HxA一 緒論全球定位系統(tǒng)(GPS是美國(guó)國(guó)防部出于軍事目地于20世紀(jì)70年代開始研制地星基無線電導(dǎo)航定位系統(tǒng),該系統(tǒng)能夠提供精確地三維坐標(biāo)、,是目前世界上最先進(jìn)、在軍事領(lǐng)域中,GPS從根本上上解決了空中、,大量GPS用戶設(shè)備已應(yīng)用于艦艇、戰(zhàn)車、飛機(jī)地導(dǎo)航；應(yīng)用于戰(zhàn)術(shù)導(dǎo)彈、戰(zhàn)略導(dǎo)彈地實(shí)驗(yàn)、測(cè)控與制導(dǎo)；,GPS技術(shù)正日益應(yīng)用到各個(gè)領(lǐng)域,但是隨著應(yīng)用地普及,一些GPS自身存在地問題也逐漸暴露出來,比如因?yàn)镚PS衛(wèi)星處于離地球表面20200km地圓形軌道上,衛(wèi)星發(fā)射功率不可能很大,其信號(hào)傳播到地球表面時(shí)是很弱地,加上國(guó)際電信聯(lián)盟對(duì)其
