Abstract

Detecting minefields in the presence of clutter is an important challenge for the Navy. Minefields have point patterns that tend to exhibit regularity such as equal-spacing and collinearity that provide potentially valuable discriminants against natural occuring clutter. These tendencies arise because of a variety of compelling factors including strategic doctrine, safety, tactical and economic efficiency, and perhaps most intriguing, the human element. In this paper, we introduce several simple procedures to detect regularity in point proceses including the empty boxes test (EBT) and its extensions, the skeptical likelihood test (SLT), and a Fourier-based method. Several possible methods to specifically detect collinearity are also discussed. The preliminary detection performance of a variety of these minefield detection methods are investigated using simulated data and a point pattern extracted from real sensor data.
