Abstract

This document describes the process of gathering information about aircrafts, its transformation into digital form. The basic methods of transformation are presented: the discrete Fourier transform, fast Fourier transform (FFT), Walsh-Fourier transform, discrete Walsh transform (DWT). On the basis of marginal analysis, it is proposed to apply the fast Walsh transform procedure in sensors. Because of its simplicity the fast Walsh transform procedure allows hardware implementation, which is capable of carrying out the conversion in real time.

Keywords:

complex tracking of moving objects, the discrete Fourier transform, frequency function, fast Fourier transform, Walsh transform, the Rademacher functions, Hadamard matrix, fast Walsh transform.
