Abstract

The invention provides a GNSS wireless occultation detecting instrument compatible with GNSS-R detection technology. The detecting instrument comprises a positioning antenna, an occultation antenna, a reflecting antenna, a radio frequency unit and an occultation processing unit, wherein the radio frequency unit is used for carrying out amplification and radio frequency filtration processing on signals received by the positioning antenna, the reflecting antenna, atmospheric occultation antenna and ionospheric occultation antenna, and inputting the generated radio frequency signals to the occultation processing unit; the occultation processing unit is used for GNSS satellite capturing and tracking through the received radio frequency signals, and calculating by utilizing the tracked signals to obtain the satellite position and speed information, carrier phase and amplitude of GNSS occultation signals, and two-dimensional delay Doppler graph of GNSS-R reflecting signals. The GNSS wireless occultation detecting instrument can achieve the purpose that GNSS occultation detection and GNSS-R sensing detection are implemented simultaneously by the same load and the same satellite.

Description

technical field [0001] The invention belongs to the fields of GNSS remote sensing detection and GNSS meteorology, and in particular relates to a GNSS radio occultation detector compatible with GNSS-R detection technology. Background technique [0002] With the improvement of GNSS (Global Navigation Satellite System), GNSS remote sensing technology has emerged as the times require and has been greatly developed. GNSS remote sensing technology uses radio waves to propagate in the earth's atmosphere, or changes in signal amplitude, phase and other physical quantities after being reflected by ground objects, to invert meteorological elements such as the earth's atmosphere, ocean and soil. At present, GNSS remote sensing technology mainly includes GNSS occultation detection technology and GNSS-R (GNSS Reflectometry) detection technology. [0003] GNSS occultation detection technology uses space-borne high-dynamic GNSS receivers to obtain phase values ​​by limb observation of GNS...
