Feasibility of the MUSIC Algorithm for the Active Protection System

Abstract

An active protection system (APS) requires accurate knowledge of the doppler frequency of an incoming projectile. In this report, I consider two methods of computing the doppler frequency the multiple signal classification (MUSIC) algorithm and power spectral density (PSD) with the use of fast Fourier transform (1024-point FFT). Normally, MUSIC has been used to improve the resolution of multiple closely spaced targets. In this application, MUSIC is used to estimate accurately a single doppler frequency. In this report, I compared the results of the estimation of the doppler frequency of an assumed head-on projectile using FSD and the MUSIC algorithm; I wanted to determine whether the MUSIC algorithm performs better than PSD in terms of accuracy and processing time.
