UAV-based aeromagnetic surveys for UXO detection and mapping applications.

June 29, 2019

UMT collaborates with American researchers to provide a method for airborne detection UXO using long-range UAV magnetometer survey approach.

The UMT Company and researchers from the Department of Geological Sciences and Environmental Studies at the State University of New York, Binghamton, in collaboration with the State Institute for Testing and Certification of Weapons and Military Equipment, Ukraine, have completed successful tests of a new method for conducting aerial magnetic surveys.

This method involves a recently developed micro-fabricated atomic magnetometer (MFAM) based on long-range hybrid-powered Cicada UAV. This solution detects magnetic anomalies from the air with unprecedented accuracy.

The experimental results suggest that such new inexpensive system may be used efficiently over wide areas both in traditional exploration geophysics and for fast airborne detection of landmines and unexploded ammunition.

The tests were conducted in September 2018 — March 2019 at the UMC site and at a test range near Chernihiv. They were intended to demonstrate the possibility of detecting various types of ammunition and military equipment, including simulated Grad MLRS rockets, large anti-vehicle landmines and 152 mm artillery shells, from the air.

Above you can see research samples of ammunition and magnetic anomalies that they create.

An effective height for each type of ammunition was determined, where the corresponding magnetic anomaly was significantly higher than the background level.

No meaningful interference from any of the UAV components, including the engine and rotors, was observed during the tests. Due to its extended flight time, Cicada UAV is useful for wide-area high-precision magnetic surveys, which creates new opportunities in exploration geophysics and unexploded ordnance detection.
