Abstract

This document presents the methods of preprocessing flight data . The data acquired during flight test contain data spikes and- noise, due to various reasons and requires processing . of data to remove spikes and noise before they are used for any analysis. For this purpose a finite difference method for editing the flight data 'to remove the spikes and Fast Fourier Transfort (FFT) method for filtering the flight data to remove the noise have been used . A software package "PREVRD' incorporating these methods has been developed . The spectral analysis via FFT to select cut-off frequency for filtering has also been incorporated in the PREPRO . The package is validated . using test example and is used successfully for processing PRITHVI post flight data .
