射电探测在天文导航技术中的应用

Radio detecting is apply in coelonavigation

天文导航是一种高精度、自主式的导航技术,在现代武器系统中起相当重要的作用。射电天文导航是一种新型的导航技术,其克服了常规光电天文导航受气象条件限制这一不利影响,为实现天文导航的全天候特性奠定基础。本文在详细分析了宇宙射电探测目标特性的基础上,提出了将太阳射电和人造卫星辐射2种不同特征的信号进行同系统接收测量的途径;详细介绍了某射电天文导航系统的接收和跟踪体制;对该系统进行了目标测角精度分析。试验数据表明,本文介绍的射电天文导航系统对太阳的测角精度已达2.7,″与光电导航性能相当。

Coelonavigation is a high precision and independent navigation technology.It plays a important role in modern weapon system.Radio coelonavigation is a new airmanship and it overcomes the disadvantage that general Electro-Optics coelonavigation is affected by the weather and blaze a way in coelonavigation domain.It establish the all-weather characteristic of the coelonavigation.This paper gives the method of making the sun radio and satellite radiation received by one system which have different signal characteristic on the base of analyzing the characteristic of radio object detailedly. This paper also introduces the receiving and tracking system of a radio coelonavigation. At last it analyses the angle measurement of this system. Test date indicates that the angle measurement of this system to the sun can reach 2.7 sec and it＇s precision is close to Electro-Optics coelonavigation＇s.
