Project G5014 “Holographic and Impulse Subsurface Radar for Landmine and IED Detection”
General project objectives
Develop a remotely-operable, robotic, multi-sensor device for detection of UXO, mines, and IEDs based on subsurface radar with imaging and target classification to discriminate dangerous targets from harmless clutter.Specific project objectives
This project will: a) directly compare the detection performance of existing holographic and impulse radars, electromagnetic induction, and Infrared imaging for landmines, UXO and IEDs under different soil conditions using rigorous statistical analyses; b) construct a high spatial resolution scanner for subsurface object detection and classification using new holographic radar and acoustic technologies and subject it to the same testing as existing technologies as in (a) above; c) develop target classification algorithms for the scanner in (b) above (based on shape, dimensions, and casing/component material characteristics) to make substantial progress in the reliability (detection rate) and productivity (false alarm rate and scanning speed) for detection of explosive devices. We will quantify the effects of soil texture, mineralogy, surface roughness, and moisture content and moisture chemistry on the probability of detection (PD) and probability of false alarm (PFA) for existing holographic and impulse radar, electromagnetic induction, acoustic, and thermal methods, and combine the best-performing methods in a single, multi-channel, high-resolution automated scanner.Project outcomes
- Identify existing highly portable, low-cost detection technologies for detection of hidden explosive devices.
- Quantify their performance under realistic and variable field conditions.
- Combine the best-performing technologies into a still-portable, and still-low-cost combined-sensor system.
- Develop target recognition methods that are effective (high Probability of Detection), efficient (low Probability of False Alarm), and operable by relatively untrained personnel (to make the system usable by locals rather than requiring experts from half a world away).
- Landmines and IEDs are still a major problem for civilians in many post conflict countries and in areas of new conflicts.
- Irregular armies often produce these explosive devices without design standards using low cost methods.
- This is the major challenge for detection technologies that must be capable of detecting also non-metallic materials and objects with different dimensions and shapes.
