ANALYSIS OF MODEL SIMULATIONS OF SPACED ANTENNA USING FULL CORRELATION ANALYSIS

Dr. Nimmagadda Padmaja, H.D.Praveena

Radar techniques have been used as powerful research tools to study clear air turbulence, cloud physics, and dynamics of consecutive storms and large-scale storms. Several ground-based techniques are used to observe and study turbulent echoes in the MST (Mesosphere Stratosphere Troposphere) region. This paper discusses Spaced Antenna (SA) technique using Full Correlation Analysis (FCA) to estimate wind velocity of simulated moving targets which is one of the important parameter used in various applications. Airglow intensities are recorded for three spaced regions in the sky, and observations of the moving pattern in the middle atmosphere is derived and recorded. The spaced antenna method is applied to model-generated, simulated data in order to extract the typical Full correlation analysis output parameters such as the apparent and true velocity. The quantity of principal interest is the estimate of „V?, the “random velocity parameter”. Correlation Analysis is a logical, simple yet effective way to estimate the wind velocity. These ideas are implemented using a mathematical model which can be simulated in any high level language. C language has been used to simulate the radar backscatter and „Origin? software for further analysis and calculation of useful quantities. The present model incorporates turbulent motions of the pattern under the presence of noise with varying turbulence strength & varying levels of noise.
