Design and simulation of a “single transmitter - four receiver” impulse GPR for detection of buried landmines

This paper describes the development of an impulse GPR configuration suitable for the detection of buried targets in natural soils - particularly the Eastern Ukraine conflict zone. The design has incorporated the requirements for a lightweight and compact system to be installed as a one component of a multi-sensor robotic scanner. The antennae have been placed in a configuration such that the footprint at 2 GHz remains sufficiently large to scan an area with dimensions larger than a typical plastic- or metal-cased landmine. The target detection and positioning algorithm, based on recorded time-of-flight data has been developed for this configuration and the analytical solution is essentially real time, simple, and easily implemented on low power ARM processors.
