Abstract
In this paper we explore the use of high-resolution array processing techniques for the detection and localization of buried objects with known shapes. A ground penetrating radar measurement geometry is considered where the scattered electric field due to an incident plane wave is observed over a linear receiver array positioned above the targets. We have modified the high-resolution algorithm MUSIC to explicitly account for the near-field physics and solved the target localization problem in two ways. The first method uses the MUSIC algorithm in a matched field processing scheme and determines both the bearing and the range of the targets. Under the second approach, the sensor array is divided into non-overlapping subarrays. The targets are assumed to lie in the far-field of each subarray ensuring a plane wave incidence over each partition. The DOAs are then found with the conventional plane wave MUSIC and the locations of the targets are determined by triangulation of the DOAs. Using simulated data we demonstrate that these techniques are quite useful for the detection and localization of metallic and dielectric mines as well as buried metallic drums. The favorable detection results are shown to hold over a wide range of soil conditions and signal to noise ratios.
