Embodiment Construction

[0028] For the first time, the present invention proposes a large elliptical orbit microwave vertical detector system for the space-borne large elliptical orbit platform, adopts an ultra-high-precision large-diameter reflective surface antenna system, and solves the problem of space-borne large elliptical orbit through a rotating scanning mirror and a two-dimensional scanning mechanism. The contradiction between the working mode of the orbital system and the width enables the microwave vertical sounder to have autonomous mobility to meet various working modes of the satellite system; the RF front-end receiving mode of the quasi-optical feeding network is used to improve the freedom of system layout and avoid the traditional feeding system. The problem of electrical performance loss caused by the defocusing of the source array; after the double-star network, the system has the all-weather quasi-real-time observation of high-latitude target areas, and the function of real-time com...

Abstract

The invention relates to a large elliptical orbit microwave vertical detector system. When an antenna beam generated by an antenna subsystem in each scanning period points to an observation target, frequency band separation and polarization separation are performed after an electromagnetic signal of the observation target is obtained; a receiver performs amplification, filtering and detection after receiving the electromagnetic signal and outputs the obtained voltage signal to a signal processing control type single machine; a calibration source body and a controller provide a microwave vertical detector system with thermal radiation calibration source brightness temperature required for rail two-point calibration; the signal processing control type signal machine performs differential reception on the voltage signal, which is subjected to analog-to-digital conversion after passing through an compensation controllable amplifying circuit; the obtained digital signal is sent to an external platform; the working state of the large elliptical orbit microwave vertical detector system is controlled according to an external instruction, and external remote sensing information, telemetry information, and remote control information exchange are controlled.
