Abstract

The invention discloses a radar's criterion module, comprising: a receiver component used to receive a radar radiation signal and to carry out AD sampling treatment on the radar radiation signal to obtain a sampling signal; and a signal processing module configured to be connected with the receiver component and a storage module so as to process the sampling signal and to transmit the obtained emission spectrum characteristics to the storage module to be stored. The signal processing module configures the trigger delay time according to the received instruction and generates a criterion signal with a preset pulse width. The criterion signal is synchronous with the pulse repletion frequency of the radar signal, and is started at the preset pulse width prior to the next sampling time point of the radar. The radar's criterion module overcomes the problem in the prior art that the standardizing and effecting is impossible, and the dynamic criterion of a radar signal can be realized, which increases the radar detection accuracy.

Description

technical field [0001] The present invention relates to radar standard effect, in particular to a radar standard effect module. 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 object of the present invention is to provide a radar calibration module, which overcomes the problem of incapable calibration in the prior art, realizes dynamic calibration of radar signals, and improves radar detection accuracy. [0005] In order to achieve the above object, the present invention provides a radar standard ...
