Gs. Wallinga et al., APPLICATION OF CEPSTRAL ANALYSIS TO RADAR TARGET DISCRIMINATION USINGE-PULSE CANCELLATION, Journal of electromagnetic waves and applications, 12(3), 1998, pp. 387-405
The cepstral analysis technique may be used to recover a transient sig
nal using only the spectral magnitude for a class of signals known as
minimum phase. This paper considers the use of cepstral analysis in co
njunction with the E-pulse method for target identification. A short r
eview of cepstral analysis and the E-pulse discrimination method will
be presented. The transient responses from several known targets will
be derived by applying an inverse Fourier transform to the target's sp
ectral response consisting of both magnitude and phase information. A
library of E-pulse waveforms will then be constructed for these known
targets. The transient response from an unknown target will be constru
cted using only the modulus of the target's spectral response. This in
formation will then be used to evaluate the performance of a discrimin
ation algorithm based on the E-pulse method. Both numerically derived
scattering data and experimentally measured data for practical target
models will be used in the analysis.
