摘要: 大氣折射誤差是影響各類無線電系統(tǒng)同步、跟蹤、導(dǎo)航、定位精度的一個(gè)主要誤差源。射線描跡法利用幾何光學(xué)原理可以實(shí)現(xiàn)對該誤差的精確修正。針對傳統(tǒng)射線描跡法無法處理異常大氣折射誤差修正的問題,該文推導(dǎo)了射線描跡法的微分形式,并基于此提出適用于任意大氣的折射誤差修正方法。選取某地面測控站對目標(biāo)的跟蹤數(shù)據(jù),驗(yàn)證了所提方法的可行性。此外,利用該方法對比分析了蒸發(fā)波導(dǎo)環(huán)境和標(biāo)準(zhǔn)大氣環(huán)境對大氣折射誤差的影響。結(jié)果表明:完全陷獲在蒸發(fā)波導(dǎo)內(nèi)部的電波引入的大氣折射誤差是最顯著的。所提方法為提高無線電系統(tǒng)在任意大氣環(huán)境下的測量精度提供一種新的技術(shù)支持。

Abstract: Atmosphere refraction error is a main error factor to affect synchronization accuracy, tracing accuracy, navigation accuracy and positioning accuracy for various radio systems. On the basis of geometrical optics, the ray tracing method can precisely make this error correction. For the problem that traditional ray tracing method can not deal with the abnormal atmosphere, ray tracing differential form is derived and then a correction method suitable for arbitrary atmosphere is proposed. The tracing data from ground station are taken to test this method. In addition, the refractive error in evaporation duct is compared with that in standard atmosphere. The results show that the refractive error of radio wave trapped entirely in the duct has the biggest influence. The proposed method provides technique support for improving the measurement precision of radio system in arbitrary atmosphere. -
