Infrared land mine detection by parametric modeling
نویسنده
چکیده
A parametric model for the infrared signature caused by a buried land mine is presented. Further, a detector is calculated for the case where the background noise can be described by an autoregressive process. The detector separately estimates the parameters of the mine and the noise in an alternating fashion. The estimates are then used in the likelihood ratio test. Simulations show that significant gains in performance can be achieved as compared to the standard detector used, which correlates the infrared image with the known mine shape and thresholds the square of the output.

Infrared processing and sensor fusion for anti-personnel land-mine detection
In this paper we present the results of infrared processing and sensor fusion obtained within the European research project GEODE (Ground Explosive Ordnance DEtection system) that strives for the realization of a vehicle-mounted, multi-sensor, anti-personnel land-mine detection system for humanitarian demining. The system has three sensor types: an infrared camera, a ground penetrating radar an...
متن کاملRandom Neural Network Filter for Land Mine Detection
The two primary measures of land mine detection performance are the probability of detection Pd and the probability of false alarm Pfa.These two measures are highly interdependent and must be evaluated together. The relationship between the two probabilities directly a ects the overall performance of the sensor in the eld. In this paper we introduce a novel false alarm non-parametric lter based...
متن کاملData Fusion for Vehicle-borne Mine Detection
This paper introduces a statisticallywell-founded evaluation of the fusion of dual-band infrared and tri-band visual imagery for detecting buried land mines using real-data. A unified Bayesian framework is presented for representing and inferring from data captured by multiple sensors of scenes that may contain buried land mines.
متن کاملControlled field experiments of wind effects on thermal signatures of buried and surface-laid land mines
Thermal signatures of buried land mines depend on a complex combination of environmental conditions, soil properties, and properties and burial depth of the land mine. Due to the complex nature of the problem most modeling and experimental efforts to understand thermal signatures of land mines have focused on the effects of one or a few variables. Of these variables, the effect of wind speed ha...
متن کاملReport to the Chairman , Subcommittee on Military Research and Development , Committee on Armed Services
Recent U.S. military operations, such as those in the Balkans, have shown that land mines continue to pose a significant threat to U.S. forces. U.S. land mine detection capabilities are limited and largely unchanged since the Second World War. A U.S. military that now uses million dollar cruise missiles, tens of million dollar aircraft, and billions of dollar ships still generally detects land ...
