Alignment calibration system based on Beidou

Abstract

The invention discloses an alignment calibration system based on the Beidou. The system comprises an antenna servo device, an emitting cabinet, a receiving cabinet and a control terminal. The emitting cabinet is connected to the antenna servo device so as to emit a signal through the antenna servo device. The receiving cabinet is connected to the antenna servo device so as to receive an echo signal corresponding to the emission signal. The criterion source or the noise source is coupled to the echo signal and amplification and amplitude limiting processing is performed on the coupled signal. The control terminal is connected to the receiving cabinet so as to control the criterion source or the noise source to be coupled into the signal and displays the processed signal. According to the invention, the problem that the radar in the prior art fails to carry out dynamic calibration is solved and dynamic calibration of the Beidou signal is achieved.

Description

technical field

[0001] The present invention relates to the field of meteorological observation, in particular to a Beidou-based calibration system. Background technique

[0002] Weather radar is an important detection method for meteorological observation. Its echo intensity Z plays an important role in local sudden and disastrous weather forecast and early warning. Similarly, the stability of echo intensity is also crucial for accurate precipitation forecasting. , especially in dual-polarization radars, has a greater impact on Zdr.

[0003] Existing radars do not have a good calibration method and cannot be dynamically calibrated. Contents of the invention

[0004] The purpose of the present invention is to provide a calibration system based on Beidou, which overcomes the problem that the radar in the prior art cannot perform dynamic calibration, and realizes the dynamic calibration of Beidou signals.

[0005] In order to achieve the above object, the present invention...
