Estimation of Power, Doppler Width, Mean Doppler and Radial Velocities for 53 MHz Pilot Active Array Radar by Using Time Series Data

Abstract: Radar data processing has been one field of data processing where there is a lot of scope for development of new and efficient tools for removing the noise, detection and estimation of desired parameters. This paper deals with the description of an algorithm for processing the data obtained from pilot active array radar which is developed at National Atmospheric Research Laboratory (NARL).The data obtained from pilot active array radar is processed for the estimation of power, Doppler width, mean Doppler ( spectral moments) and radial velocities using specific windowing technique. This data processing done is partly on-line and partly offline. The on-line processing significantly compresses the data via time averages and usually produces power spectra and off-line calculations involve parameter extraction. Data processing of recorded experimental data is performed by the developed MATLAB code and the results were plotted. The derived velocity components are validated by comparing the velocity components obtained from GPS data at NARL.
