Effect of soil perturbation on radar identification of buried object using matrix pencil method

Abstract

This paper presents an analysis of effect of soil perturbation on radar identification. A matrix pencil method is utilized to extract poles from the late-Time portion of the scattering transient response of the object. Simulations are conducted to evaluate the effect of soil perturbation on these poles. Simulation results shows the perturbation of soil, especially in term of dielectric constant and object depth, have a strong effect on poles. An appropriate Euclidean distance is introduced to classify the object buried in soil with its different properties.
