Paper Abstract

Ground Penetrating Radar has been applied for several years to the problem of detecting both anti-personnel and anti-tank landmines. Most of the evaluation effort has focused on obtaining the end-to-end performance metrics (e.g. Pd and pfa ) of complete detection systems. This is the third in a series of papers in which we focus on the specific performance of one critical component of GPR systems: the antenna subsystem. In this paper, we examine several free-space characteristics of Planning Systems Inc. Archimedean Spiral Antennas. Specifically, we (1) investigate a spurious signal response observed with a large metal plate reflecting target, (2) determine gain and phase properties of these antennas, (3) calculate the antennas' impulse response, and (4) image several targets to validate our approach.
