Effects of Soil Condition on Landmine Discrimination Using GPR Sensor
It is well known that a huge number of buried landmines in the post-war countries are still active, and that many civilians are killed or injured by landmine related accidents every year. Therefore, detection and clearance of buried landmines is a very important issue. Metal detectors are the almost universally available fielded devices for landmine detection, but they have great difficulty in ...
متن کاملUxo Discrimination Using Time Domain Electromagnetic Induction
An explosive ordnance is a munition that is either launched or fired with the intent of detonation at a specified target. An unexploded ordnance (UXO) is an explosive ordnance that, due to some malfunction, remains undetonated. As a result, the ordnance can be found at the ground surface, partially buried, or buried at a depth of up to 8 m beneath the surface. Practical and cost-effective strat...
متن کاملImproving UXO discrimination using magnetic quadrupole moments
Currently there are no UXO discrimination techniques based on total-field magnetic sensor data that rely on multipole expansion parameters of higher order than the dipole. In some cases, however, it can be advantages to describe a UXO target with both dipole and quadrupole parameters. In this paper, we examine the properties of the quadrupole moment and illustrate them using a synthetic example...
متن کاملCharacterization of UXO-like targets using broadband electromagnetic induction sensors
We have inverted broadband electromagnetic induction data over an isolated target to determine its electrical conductivity, magnetic permeability, radius, and depth using a sphere model. Studies using synthetic data of a concentric, broadband, electromagnetic sensor indicate that the technique is dependable and produces fast-converging solutions. The geometrical parameters obtained through this...
متن کاملEffects of the ground surface on polarimetric features of broadband radar scattering from subsurface metallic objects
Throughout the world, the problem of buried unexploded ordnance (UXO) poses an enormous, persistent, and expensive problem. While UXO generally consist of sizable bodies of ferrous metal and can therefore be detected, with current technology it is extremely difficult to distinguish them reliably from typically widespread pieces of clutter. Thus the problem is one of subsurface discrimination. O...
