Embodiment Construction

[0057] The present invention will be further explained below in conjunction with the accompanying drawings and specific embodiments.

[0058] Such as figure 1 As shown, a UHF wireless microwave data-driven dew point-frost point temperature field reconstruction method includes the following steps:

[0059] S1. Obtain the microwave data of multiple UHF wireless microwave links in the research area during the research period; obtain the attenuation signal of the microwave data in the atmosphere; obtain the humidity and temperature data of the weather station;

[0060] The microwave data of the UHF wireless microwave link has random errors and noises, which are recorded as:

[0061] {y i}={f i}+{e j}, j=1, 2, ..., N (1)

[0062] Among them, {yi} is the dynamic test data, {fi} is the smooth measurement result, {ej} is the random error, and N is the number of data;

[0063] The moving average method can be used to filter random errors, and the obtained microwave data is more a...

Abstract

The invention discloses a dew point-frost point temperature field reconstruction method driven by ultra-high frequency wireless microwave data, which comprises the following steps: obtaining microwave data and microwave data The attenuation signal and the humidity, temperature and other data of the weather station; establish a dew point-frost point temperature inversion model based on wireless microwave characteristic attenuation, and calculate the dew point temperature at the midpoint of each link; use interpolation method to reconstruct high spatial and temporal resolution The spatial two-dimensional dew point-frost point temperature field of , and corrected according to the measured data of weather stations. The present invention effectively utilizes the existing high-density ultra-high frequency wireless microwave communication network, greatly improves the temporal and spatial resolution and monitoring accuracy of the dew point-frost point temperature field, and realizes the transformation from zero-dimensional dew point-frost point temperature "point" to Breakthrough of the two-dimensional dew-frost temperature "field".

Description

technical field [0001] The invention relates to the application field of a new generation of communication technology, in particular to a dew point-frost point temperature field reconstruction method driven by ultra-high frequency wireless microwave data. Background technique [0002] The temperature at which the unsaturated air lowers its temperature while keeping the absolute water content constant, so that it reaches a saturated state is called the dew point temperature. Generally, the temperature above 0°C is called the "dew point", and the temperature below 0°C is called the "frost point". The dew point / frost point temperature is the main humidity parameter describing the gas humidity (water vapor content), and is also an important indicator affecting the comfort of the human body. have an important guiding role. Therefore, monitoring the dew point / frost point temperature value and its spatial distribution is a work of great practical significance. [0003] At present...
