Abstract

A conical scanning space-borne microwave radiometer system based on wireless transmission comprises a conical scanning space-borne microwave radiometer and a set of wireless transmission equipment. When the conical scanning space-borne microwave radiometer system works in a slip ring transmission mode to transmit data, the wireless transmission equipment A and the wireless transmission equipment Bare in a shutdown state, an integrated processor is connected to a slip ring through a bus interface, and at this time, the data is transmitted between the integrated processor and a detection head through the slip ring. When the conical scanning space-borne microwave radiometer system works in a wireless transmission mode to transmit the data, the wireless transmission equipment A and the wireless transmission equipment B are started and work jointly, a space communication link between the integrated processor and the detection head is established, and remote sensing data and remote controltelemetry information are transmitted between the integrated processor and the detection head. The problem of data loss or data misrepresentation due to the characteristic of transient interruption ofthe slip ring is solved, the reliability of signal transmission of the conical scanning space-borne microwave radiometer system is improved, and the in-orbit service life of the conical scanning space-borne microwave radiometer system is prolonged advantageously.

Description

technical field [0001] The invention relates to a conical scanning spaceborne microwave radiometer system based on wireless transmission, which belongs to the technical field of space microwave remote sensing. Background technique [0002] The spaceborne microwave radiometer system used for ocean observation, in order to ensure that the incident angle of the antenna beam to the ground is constant and the size of the footprint formed by the beam on the ocean surface is consistent, so as to facilitate the inversion of various ocean parameters, the design often uses Cone scanning method. [0003] The conical scanning satellite-borne microwave radiometer system is divided into a rotating part and a fixed part. The antenna, receiver, collector, correlator and other equipment are all located in the rotating part, which requires the establishment of a communication link between the rotating part and the fixed part. The microwave remote sensing data collected by the collector, corr...
