Abstract
Wind profile measurement in the earth’s lower atmosphere using remote sensing technology has play most important role in emerging trends. SODAR, a remote sensing system which is using to measure the turbulence in the wind, through transmitting an acoustic pulse in to the earth’s atmosphere and receiving the scattered signal. Among the various remote sensing techniques, to obtaining wind patterns in the earth’s lower atmospheric layer, acoustic wind profiler is the best technique when compare to other techniques. Here in this paper, a phased array antenna has been developed for the atmospheric wind measurements. The system has the capability to remotely measure atmospheric horizontal and vertical winds up-to 1000 meters within the earth’s atmospheric boundary layer. This phased antenna has designed with 8 x 8 array tweeters to obtain accurate side lobes of the transmitted signal. The Intend of this paper is to compute the mathematical algorithms of the 8 x 8 acoustic phased array antenna using a scientific software, MATALB. MATLAB is a numerical computing software with rich in displaying graphical representations. When observed the result from the traditional computing techniques and this novel computing methodologies, this novel computing has reached the real-time values measured by the system.
