Problems solved by technology

[0002] In ground-based remote sensing systems for measuring the intensity, vertical velocity, and spectral width of precipitation clouds or precipitation at various altitudes, meteorological radars usually use pulse-based radars. However, due to the limitation of the transmitted pulse width, the distance resolution of pulse radars is low. It is not suitable for refined weather detection, and it is difficult to obtain more accurate weather detection data

Abstract

The invention relates to a meteorological radar system based on continuous wave system and a control method, wherein the system comprises an emission extension which is used to receive a linear frequency modulation continuous wave signal from an extension and obtain a continuous wave emission signal after amplification processing, and output the signal to an emission antenna module; a reception extension which is used to output the linear frequency modulation continuous wave signal to the emission, receive a meteorological echo signal from an antenna module, and output the signal to a digital processing extension after frequency conversion amplification processing; an emission antenna module, which is used to emit the continuous wave emission signal; a reception antenna module, which is used to receive the meteorological echo signal; and a digital processing extension, which is used to receive the signal from the extension and process it to obtain the meteorological data information and perform instruction control to the radar system state at the same time. According to the continuous wave system, the emission signal employs continuous wave signal, which has a higher distance resolution compared to a pulse system radar, therefore the meteorological radar system is especially suitable for refined meteorological detection.

Description

technical field [0001] The invention relates to the field of weather radar, in particular to a weather radar system based on a continuous wave system and a control method for the weather radar system. Background technique [0002] In ground-based remote sensing systems for measuring the intensity, vertical velocity, and spectral width of precipitation clouds or precipitation at various altitudes, meteorological radars usually use pulse-based radars. However, due to the limitation of the transmitted pulse width, the distance resolution of pulse radars is low. It is not suitable for refined weather detection, and it is difficult to obtain more accurate weather detection data. Contents of the invention [0003] The object of the present invention is to provide a weather radar system based on continuous wave system and its control method. The distance resolution of the weather radar system is high. Compared with the traditional pulse system weather radar, it has obvious advant...
