Examination of soil effect upon GPR detectability of landmine with different orientations

Abstract

Landmines represent a serious environmental problem for several countries as it causes severe injured and many victims. In this paper, the response of GPR from different parameters of the landmine targets has been shown and the data is correlated with observed field experiment made in 2012 at Miami Crandon Park test site. The ability of GPR for detecting non-metallic mines with different orientations was revealed and soil effect upon the GPR signal was examined putting into consideration the soil parameters in different locations in Egypt such as in Sinai and El Alamein. The simulation results showed that PMN-2 landmine was detected at 5 cm and 15 cm depths, even at the minimum radar cross section vertical orientation. The B-Scan (2D GPR profiles) of PMN-2 target at 15 cm depth figured out high reflectivity for Wadi deposits due to large contrast between PMN-2 landmine material and soil of sand dunes.

Estimation of Handheld Ground-Penetrating Radar Antenna Position with Pendulum-Model-Based Extended Kalman Filter

“…Due to a relatively large GPR antenna beamwidth, the same buried objects are illuminated many times from different antenna locations and consequently from different distances. Therefore, the echo signals form hyperbolic structures visible in the B-scans [14,23,39,46,47]. An example of such a structure for a single-point object is shown as a red hyperbole in Figure 2b.…”

“…Apart from the MDs, radar technology has been successfully employed for scanning near-underground surfaces in search of mines, improvised explosive devices (IED), and other explosive remnants of war [6][7][8][10][11][12][13][14]. Ground penetrating radar (GPR) is a general term used with respect to techniques using radio waves, typically in a frequency range from several MHz to several GHz, to acquire information about objects buried underground or hidden under/behind any other concealing obstacles, surfaces, etc.…”

“…Three types of visual presentations of GPR radargrams are used in practice [3,14,16,21]. A single echogram was obtained for only one GPR antenna position with coordinates (i, j) is a one-dimensional signal representation, called an A-scan (Figure 2a).…”
