L3Harris’ newest AN/PSS-14 design (aka Handheld Standoff Mine Detection System or HSTAMIDS) provides a unique solution to the global community’s urgent need for dual sensor detection that addresses current and evolving munitions threats, from conventional landmines to buried explosive hazards and their associated components.

Handheld Standoff Mine Detection System

By leveraging more than a decade of countermine experience, both in developing the technologies and in training thousands of Warfighters in the safe operation and effective use of the U.S. Army’s HSTAMIDS, as well as incorporating the firsthand feedback provided by our customers, L3Harris has developed a package of product improvements that address the most compelling operational needs.

Leveraging the experience gained through the development and deployment of the earlier models of the AN/PSS-14, which included an advanced metal detector (MD) combined with a unique Ground Penetrating Radar (GPR), L3Harris has improved upon previous performance and modified sensor(s) technology to address new and urgent requirements. The new capability to operate in separate modes or concurrently has dramatically increased the breadth of functionality of the latest 2015 model AN/PSS-14 while increasing ease of use.


In countermine mode, the GPR and MD work simultaneously using unique data fusion algorithms to allow an operator to effectively and efficiently recognize mines and disregard metallic debris. The 2015 model duplicates the demonstrated capability of the AN/PSS-14 Handheld Standoff Mine Detection System to increase the speed and safety of military and humanitarian demining operations by limiting targets to real threats and allowing operators to focus upon them.

A separate GPR-only mode has been added that includes a parallel algorithm for processing GPR signals independent of MD signals, which allows the operator to search for and detect completely non-metallic targets.

In order to provide the highest level of operational security, the 2015 Model provides a concurrent CM/CEH mode for missions involving completely unknown threats or targets. In this mode, both the Countermine and CEH processes are operating simultaneously, ensuring that the operator can find all types of threats including both metallic and non-metallic.

L3Harris’ ground penetrating radar sensors, combined with advanced sensor processing, discrimination, and new CEH detection algorithms have demonstrated the ability to detect low metal and even non-metallic EH threats.

New Versatility. 
By decoupling the GPR from the MD, the GPR can now detect and discriminate larger, deeply buried targets from shallow clutter and background.

Increased Security. 
Based on a stepped frequency continuous wave (SFCW) technique rather than the more common pulsed approach, the 2015 Model GPR has been demonstrated to be inherently more impervious to radiated RF.

Simplified Operation, Faster Training. 
By providing simplified target detection tones and voice commands, and GPR system initialization no different from standard operation, L3Harris anticipates no additional training burden resulting from the added new capabilities. No pre-buried calibration targets are required prior to operation.

Fast Reaction: Off-to-Operating within minutes.
 Includes on-the-fly initialization and update for all modes (including CEH mode) As a result, the system can now be ready for use in less than 2 minutes in any terrain.
