Research on Treatment of Transient Response for Buried Target in Large Forest

Abstract

Buried forests have complex meteorological conditions and carbon storage functions. Deep
analysis on time transient backscatter response is beneficial to obtain the target feature
information. In this paper, the theoretical deduction shows that the energy of surface reflection
at different polarization are equal in GPR early-time response stage. Utilizing the relationship of
maximum singular value and transient response, the suddenly drops of maximum singular value
time is the start of the late-time response stage. With the numerically simulated backscattered
response of the slender cylinder buried dry sand environment, the results prove that this
processing method can separate the late-time response effectively.
