2 Khz Mono Pulse Acoustic Signal Generation for SODAR Application Using PC Sound Card And MATLAB graphical User Interface
Journal Title: International Journal of Research in Computer and Communication Technology - Year 2013, Vol 2, Issue 12
Abstract
The SODAR (Sound Detection and Ranging) is an instrument that to measure the wind profile in the lower atmosphere of the earth. The volume measurement of the wind profile by remote sensing device, like SODAR have a great advantage compared to point measurements in a one height. In SODAR, acoustic pulses are sent vertically and at a small angle to the vertical. A thus transmitted sound pulse is scattered by the fluctuations and gradients as well as wind shear. There are five basic parameters that determine how the SODAR sends the beam. These are Transmit Frequency (FT), Transmit Power (PT), Pulse Length (τ), Rise Time (βτ) and Time between pulses (T). There are two further parameters, namely “Tilt angle” and “Half beam width”, which describes the beams of the antenna, but cannot be controlled by the software like MATLAB. MATLAB is a high-level language and interactive environment for computations, visualizations and programming. This language tool, and built-in mathematical functions will enable you to explore multiple approaches and reach a solution faster than with spreadsheets or traditional programming languages, such as C or C++ or VC++. Among the five basic parameters mentioned above, Transmit Frequency (FT), Pulse Length (τ) and Time between pulses (T) are controlled by designing the Graphical User Interface (GUI) of MATLAB.GUIs also known as graphical user interfaces or UIs provide point-andclick control of software applications, eliminating the need to learn a language or type commands in order to run the application.Thus using this GUI, user desired values of a SODAR beam can be generated. This paper is divided into four different layers such as user layer, application layer, operating system layer, and Hardware / Physical layer. The user layer gives the input to the application layer by mouse click or inputs through GUI icons. The application layer performs the signal processing such as parameter determination and further communicates with the operating system layer. The operating system layer acts as a bridge between hardware layer and application layer. Finally the Hardware / Physical layer takes care of commands executions, which are given by operating system layer.The advantage with this design of GUI replaces the ancient analog system using for beam generation.
