Design & Simulation of Graphical User Interface For SODAR System Using VC++

Acoustic remote sensing is the Science and engineering of obtaining the spectral, spatial and temporal information about the state of the first few hundred meters of the atmosphere above ground without coming into physical contact with it. The development of the acoustic methods for atmosphere research essentially relies on achievement in theoretical and experimental investigation in sound propagation in the atmosphere. The principle of acoustic remote sensing of the atmosphere involves the Bragg scattering sound, Gilman was the first person to use the term SODAR from the acronym: Sound  Detection And Ranging, has been used as a means to study the structure of the lower atmosphere. In this paper, an audible ‘beep’ is beamed up into the atmosphere and very faint echoes from features within the air itself are detected back at the ground. Microsoft VC++ is a powerful object – oriented application integrated development environment. This object – oriented program are rich in structure, methods and attributes. The object – oriented frame work provides an important enabling technology for reusing software components. In VC ++, these frameworks are supported by Microsoft Foundation Classes (MFC). The MFC is used to develop the necessary visualization tools as it simplifies in writing the programs and it also provides many High level features that can save considerable coding effort. In this paper, designed a powerful GUI function facilitate the time – height plots in such a way that the plot can be stored, retrieved and processed to eliminate unwanted fixed echo signal, which are of non-atmospheric origin for sodar system. 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.
