Sodar Wind Profiler System

Best solution for high altitude wind detection / Lost Cost / Portable

Sodar Wind Profiler System is an advantageous product that has emerged in recent years to measure high altitude wind, which is different from the traditional wind measurement tower.

Avoiding the preliminary construction cost and the high investment in operation and maintenance cost later, and also avoiding the duplicate construction problem arising from the need to change the monitoring location.

Sodar Wind Profiler System is highly portable and has the advantage of low cost.

Sodar Wind Profiler Definition

Sodar is a meteorological instrument used as a wind profiler to measure the scattering of sound waves by atmospheric turbulence.

SODAR systems are used to measure wind speed at various heights above the ground, and the thermodynamic structure of the lower layer of the atmosphere.

Sodar systems are in fact nothing more than sonar systems used in the air rather than in water.

More specifically, since they operate using the Doppler effect with a multi-beam configuration to determine wind speed, they are the exact in-air equivalent to a subclass of sonar systems known as acoustic Doppler current profilers (ADCP).

Other names used for sodar systems include sounder, echosounder and acoustic radar.

CHAPTER 2:

Sodar Wind Profiler Working Principle

Acoustic radar is a kind of radar equipment (i.e., wind speed and direction measurement equipment) that uses acoustic waves audible to the human ear to measure the flow of atmospheric air.

The acoustic radar antenna is composed of multiple transceiver reversible piezoelectric transducer phased array, transceiver shared.

The acoustic radar works by transmitting a short pulse of multi-frequency coded acoustic signal to the low altitude atmosphere. The pulse signal has the basic characteristics of sound and propagates directionally in the atmosphere; when the emitted signal encounters the turbulence in the atmosphere, various scattering occurs, in which the backscattered echo differs from the emitted direction by 180°.

The acoustic radar antenna receives the backscattered echo, processes the echo signal in this direction, obtains the Doppler shift in the radial direction, and then converts it into radial wind speed.

CHAPTER 3:

Sodar Wind Profiler Composition

The acoustic radar system consists of four parts: phased array antenna signal generator/high frequency speaker, acoustic power amplifier, signal receiving processor and fixed device.

ZAS phased array wind sound measurement radar system consists of antenna array, detection processing device.

ZAS antenna array consists of 64 piezoelectric transducers. The system has 6 working frequency points. The minimum measurement height is 10m, the average measurement height is 200m (40dBA, 15°C, 70% relative humidity), and the maximum measurement height is 300m (optional).

ZAS detection processing device adopts embedded industrial-grade high-performance DSP processing module, including detection signal generation, reception pre-processing, detection processing, signal accumulation and other functions.

Processing results support standard Ethernet interface output.

Sodar Wind Profiler System FAQs

Here are some common questions about Sodar Wind Profiler Systems. We will update them regularly through customer feedback.

I hope you can find the answers here. If you have more questions, please email to us.

What is a Sodar?

Sodar is a meteorological instrument used as a wind profiler to measure the scattering of sound waves by atmospheric turbulence. SODAR systems are used to measure wind speed at various heights above the ground, and the thermodynamic structure of the lower layer of the atmosphere.

How does a Sodar works?

A Sodar works by sending out a sound pulse (beep) and recording the sound as it’s scattered off atmospheric turbulence back to the Sodar. The principle is very similar to the well known radar technique which transmits a radio wave and records echoes from objects.

How is impact of rains on Sodars?

Actually the rain drops size being much smaller than the acoustic wavelength, their down speed is not detected by sodars. However poorly designed Sodars will exhibit spurious down speeds due to high harmonics of either 50 Hz or 60 Hz harmonics of the power supply in humid conditions.

How is impact of snow and fog on Sodars?

Both snow and fog will make the Sodar reflective signal stronger, but when there is a snowstorm, it needs to be done every now and then to clear the surface adhesion and use the mode of heating the transmitter.

How is impact of ambient acoustic noise on Sodars?

Ambient noise will affect the monitoring level and the reception of the signal, although it can be filtered by the algorithm, but the monitoring data has actually been separated from the real environment, so we require that the ambient noise should preferably be lower than 40dBA.

How is impact of ground clutter on Sodars?

We have minimized the impact of ground obstacles on the signal with our algorithm, but we still recommend that you try to detect in an open area to get more accurate data.

How is impact of high winds on Sodars?

High wind pairs produce higher ambient noise and reduce the measurement height range. We have done the optimization process by structural design to reduce the effect of turbulence and measure in the horizontal direction to 30m/s range.
