Space vehicle inspection device based on GNSS reflection signal

Abstract

The invention discloses a space aircraft detecting device based on GNSS reflected signals, comprising a computer, a right-hand antenna, a left-hand antenna, a Doppler relay mapping receiver and an inversion target position resolving unit; the right-hand antenna and the left-hand antenna are respectively connected with an input interface of the Doppler relay mapping receiver and the computer is connected with an output interface of the Doppler relay mapping receiver; the inversion target position resolving unit is stored in the computer. The detecting device comprehensively makes use of the received direct signals emitted by GNSS and the received direct signals emitted by GNSS which are reflected by the space aircraft to acquire the coordinates (X0, Y0 and Z0) of the space aircraft under a geocentric rectangular coordinate.

Description

technical field [0001] The present invention relates to a detection device, more particularly, to a space vehicle detection device based on GNSS reflection signals. Background technique [0002] After the 1990s, the fastest and most effective development of military technology is the information revolution based on satellite technology, which is marked by the organic combination of outer space, air early warning, and sea, land and air precision long-range strike forces. Correspondingly, the coverage of sea control will be further expanded to outer space and deep waters, and its connotation and means of realization will be further developed into the combination of land, sea and air long-range precision strike technology driven and guided by the two major technology chains of outer space and air early warning. and the force structure as it is applied to maritime operations. Precision strike technology depends on the accuracy of target detection. If the enemy's target cannot ...
