Ku/V waveband double-frequency radiometer

Abstract

The present invention provides a Ku / V waveband double-frequency radiometer. The Ku / V waveband double-frequency radiometer comprises two independent front wireless signal reception processing channels, one of the front wireless signal reception processing channels is used for receiving Ku waveband signals and performing signal processing to form a digital signal sequence for outputting, and the other one thereof is used for receiving V-waveband signals for signal processing to form a digital signal sequence for outputting, wherein the front wireless signal reception processing channels alternately obtain corresponding frequency spectrum movement signal sources through accessing the same frequency synthesizer; and the Ku / V waveband double-frequency radiometer also comprises the frequency synthesizer, the frequency synthesizer is configured to receive control data to form stable reference frequency for outputting so as to ensure the signal intensity of subsequent synthesis frequency. The Ku / V waveband double-frequency radiometer ensures high-quality scanning performance of the wireless signals received by the front and the stable and high-speed sampling processing performance, ensures the high time consistence of different frequency-band signals, and is simple in signal processing structure and stable and reliable in processing process so as to be helpful for a back-end processing device to realize the accurate measurement of the content of the steam and the cloud liquid water in the air.

Description

technical field [0001] The invention relates to a wireless signal receiving device, in particular to a heterodyne down-conversion wireless signal receiving device. Background technique [0002] The measurement of the atmospheric environment in the prior art is mostly based on the measurement of the single-band radiometer, which will result in discretization of the acquisition elements of the measurement data. Due to the higher and higher requirements for the measurement accuracy of atmospheric humidity and temperature, single-band radiometers can no longer achieve the necessary accurate testing, so the demand for dual-band radiometers is increasingly urgent. The existing Ku-band and V-band dual-band radiometers have higher detection accuracy than the previous low-frequency single-band radiometers because of their higher frequency. However, the Ku-band and V-band belong to the millimeter wave band, which has higher requirements for the technical requirements of the front-end...
