Dual Sensor Technology
The AN/PSS-14 revolutionizes landmine detection by combining ground-penetrating radar (GPR) and highly sensitive metal detector (MD) technology using advanced data fusion algorithms. This unique combination enables the system to detect, reliably and consistently, anti-personnel (AP) and anti-tank (AT) mines. It is capable of rejecting the detection of metallic clutter, increasing operator confidence and efficiency.

In order to maximize operational effectiveness and efficiency, the AN/PSS-14 offers a high probability of detection (Pd) with a minimal false alarm rate (FAR). The system maintains this level of performance across all environmental conditions and soil types, including heavily mineralized soils.

Specifically designed for the soldier, the AN/PSS-14 went into full-rate production as the U.S. Army’s standard mine detector in 2006.

Ground Penetrating Radar
The GPR is based on a wide-band, coherent, stepped frequency radar transceiver. The search head contains one transmit and two receive antennas. The transmit antenna produces continuous wave, low power radar. As the search head passes over the surface of the ground and radar waves strike a discontinuity in the soil, some waves are reflected back to the receive antennas and processed by the system.

Advanced Metal Detector
An advanced metal detector coil encompasses the diameter of the sensor head. Passing current through the MD coil creates an electromagnetic field that induces an electrical current in any metal object that is buried in the soil. The sensor head detects this secondary electromagnetic field and responds with an alarm, alerting the soldier to the possible presence of a mine.

Sensor Fusion
Exceptional performance is achieved using unique data fusion algorithms, which allow the operator to effectively discriminate between metallic clutter and actual mines. The algorithms are based on terrain modeling using a real-time novelty (RTN) methodology. As the operator advances, the terrain model updates continuously, enabling the system to adapt automatically to varying soil conditions. The operator is alerted to potential mines by an audio signal.

AN/PSS-14 is a controlled item under the International Traffic In Arms Regulations (ITAR). It may be exported with proper authorization by the U.S. Department of State.
