Investigation on echo characteristics of ground penetrating radar for elliptical target

A full study and analysis of the electromagnetic scattering echo characteristics of targets with different shapes is helpful to better interpret and image the target radar detection echo data. The shape of elliptical target is closer to that of many practical targets, so it is meaningful to study the electromagnetic scattering echo characteristics of elliptical target. The finite-difference time-domain model of radar detection of elliptical targets with different azimuth angles is established. Through numerical calculation, the influence of azimuth angle of ellipse on target radar echo characteristics is analyzed, which provides a theoretical basis for elliptical target echo detection in radar detection.
