Description
Technical Field
The invention relates to a sounding turbulence measurement device and a measurement method thereof, in particular to a recyclable sounding turbulence measurement device and a measurement method thereof, and belongs to the technical field of atmospheric sounding measurement.
Background
When laser is transmitted in turbulent atmosphere, the wave front of the laser is distorted due to the fluctuation of the refractive index in the atmosphere, and turbulent effects such as beam drift, spot expansion, light intensity fluctuation and the like are caused. The atmospheric coherence length and the atmospheric refractive index structural constant Cn2 are two important parameters for characterizing the degree of advance of atmospheric turbulence, and the relationship between the atmospheric coherence length and the turbulence intensity is
Where k is the wavenumber, h0 is the height of the instrument from the ground, phi is the zenith angle, and W (h) is a kernel function which can be expressed as
The temperature pulsation meter obtains CT2 by measuring the temperature pulsation difference between two points, obtains the average value of temperature and air pressure by measurement, and substitutes the average value into the relational expression of CT2 and Cn2 to obtain the atmospheric refractive index structural constant.
From Kolmogorov's theory of locally uniform isotropic turbulence, it is known that the structure constant between two points in the turbulence inertia zone is only related to the 2/3 th power of the distance between the two points, independent of the position and relative direction of the two points, and thus the temperature relief structure function and the refractive index relief structure function can be expressed in small scale
Wherein DT and Dn are structural functions of temperature and refractive index, respectively; CT2 and Cn2 are the structural constants for temperature and refractive index, respectively, and r is the distance between the two points.
The refractive index of the earth's atmosphere in troposphere heights <17km over the visible light band is denoted as [10 ]:
wherein P is the atmospheric pressure unit: 100Pa, T is the thermodynamic temperature (unit: K, lambda is the unit of wavelength of light wave: μm. differentiation of both sides of the above formula gives:
at a certain fixed height, the air pressure variation is relatively small and negligible, and the refractive index variation dn is mainly generated by the temperature dT. Thus, the atmospheric refractive index structural constant Cn2 and the temperature structural constant
Is [10]]：
Therefore, Cn2 can be calculated by obtaining the pressure P, the temperature T, and the temperature difference between the two points. The temperature pulsation sonde has simple principle, mature technology and easy implementation, so the measuring method is widely applied. But the detection equipment carried by the device is difficult to recover and has higher cost; the batteries in the equipment can cause environmental pollution.
