Title:Use of the Fractional Fourier Transform for radar Target Identification using the Singularity Expansion Method

Abstract: This presentation will discuss the Fractional Fourier Transform for estimating parameters of damped sinusoids utilizing both early and late time transient scattering data contaminated by noise. Transient scattering responses are composed of damped sinusoids at late times and impulse-like components at early times.  Due to the impulse-like components, it is difficult to extract meaningful damped sinusoids.  In this study the entire noisy time domain response is used to extract the signal parameters of interest. The fractional Fourier transform (FrFT), especially the half Fourier transform (HFT) is used to analyze the data for parameter identification. Impulse or Gaussian-like pulses can be easily separated from the damped exponentials in the HFT domain, as they have similar functional representations. Results from several examples show that the new technique is applicable for noisy signals that are composed of damped exponentials and pulse-like components.
