Distance: S=C [(Ta2-Ta1)-(Tb2-Tb1)] (C is the light velocity).
The application using the electromagnetic wave different principle of spread speed in different media, using traditional UWB sensor as
A kind of new usage mode is placed into the two sides of object under test, and medium directly affects the detection data of UWB sensor, or
Say that the data of UWB sensor detection are influenced by the medium that electromagnetic wave is passed through.The electromagnetic wave of UWB sensor release has passed through sky
The accounting of gas and water, air and water on the electromagnetic wave motion path of UWB sensor directly affects the measurement number of UWB sensor
According to.The spread speed of electromagnetic wave in water is less than the spread speed in air.Wherein accounting of the water on Electromagnetic Wave Propagation path
It is linear with the data of UWB sensor detection.
The speed that electromagnetic wave passes through detection space passes through the speed in detection space much larger than rainwater, it is believed that in electromagnetic wave
Shuttles detected in the time in space, and rainwater is static relative to the position in detection space.UWB sensor can measure one at this time
Moment, the ratio θ of the volume of the volume and detection space of water.The accounting of water i.e. in the detection space.It can be in certain space
The accounting of water is as a kind of index for measuring precipitation.θ can be used as the index for measuring precipitation.The big Shi Zedai of the precipitation guide line numerical value
Rainwater content in table air is high, and precipitation intensity is big.UWB sensor can measure the index in real time.
Precipitation intensity is for the existing index for measuring precipitation.Precipitation intensity refers to the precipitation within the unit time.
The ratio of the depth and time that can accumulate after water landing in detection space is precipitation intensity R.Detection space volume be
V1, floor space S1 are highly H1, meet following formula, V1=S1*H1.V1* θ is the total volume for detecting water in space.V1*
θ/S1 is the depth that can be accumulated.The water of the volume passes completely through T1 the time required to detection space.Precipitation intensity R meets following public
Formula R=(V1* θ/S1)/T1.V0 is the speed that rainwater falls, T1=H1/v0.Simplify above formula R=θ * v0.
As an alternative embodiment, using high-speed camera shooting image and image can be compared, to obtain
The speed v0 of rainwater.And then obtain precipitation intensity index R.
As a kind of specific embodiment, there is corresponding close with rainwater volume and precipitation intensity in the speed v0 of rainwater
System.Certain precipitation intensity corresponds to the raindrop of certain volume and the sinking speed of raindrop.That is the volume of water and detection are empty
Between volume ratio θ and the sinking speeds of raindrop there are corresponding relationships.The sinking speed range of raindrop can be obtained according to θ,
Range mean value is as v0.And then obtain precipitation intensity index R.
The basic principles, main features and advantages of the invention have been shown and described above.The technical staff of the industry should
Understand, the above embodiments do not limit the invention in any form, all obtained by the way of equivalent substitution or equivalent transformation
Technical solution is fallen within the scope of protection of the present invention.
