Embodiment Construction

[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0024] A general space vehicle detection system includes a plurality of navigation satellites, a plurality of space vehicles and a plurality of space vehicle detection devices, and the space vehicle is also referred to as a moving target to be detected by the space vehicle detection device. The detection of the moving target is mainly to obtain the position of the moving target in the earth-centered Cartesian coordinate system.

[0025] see figure 1 Shown, in the present invention, shown in the figure is the space vehicle detection system that a plurality of navigation satellites, a space vehicle detection device and a space vehicle constitute; Said space vehicle detection device receives the 1st navigation satellite, the 1st navigation satellite on the one hand, 2 navigation satellites, the 3rd navigation satellite, ..., the Nth navigation satellite transmi...

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 ...
