Mini-H: Optimal Versatility, Minimal Footprint

Miniature Handheld Buried Threat Detector Miniature Handheld Buried Threat Detector

L-3 CyTerra’s Mini-H provides a unique solution to the international community’s urgent need for a new lightweight, dual sensor detection system to address current and evolving threats from buried bulk explosives and conventional landmines. Leveraging more than a decade of countermine experience derived from fielding and training thousands of soldiers in the safe operation and effective use of the US Army’s AN/PSS-14 (HSTAMIDS) and incorporating the firsthand feedback provided by our customers, L-3 CyTerra has developed a package of product improvements that address the most compelling needs of these users. Only L-3 CyTerra’s Mini-H can offer this exceptional performance in a compact, streamlined new design.

System Highlights

  • Low-Metal and Non-Metal buried bulk explosive and landmine detection
  • Three distinct modes – Countermine, Bulk Explosives Detection and concurrent
  • Compact and lightweight
  • “Instant-on” operation capable
  • Jammer compatibility


Leveraging the experience gained through the development and deployment of the AN/PSS-14, an advanced metal detector (MD) combined with a Ground Penetrating Radar (GPR), L-3 CyTerra has improved upon existing performance parameters to address new and urgent requirements. The new capability to operate in three separate modes has dramatically increased the breadth of functionality of the Mini-H.

Countermine (MD/GPR)

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 Mini-H capitalizes on the demonstrated success of the AN/PSS-14 Handheld 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 on them.

Bulk Explosives Detection

By adding a separate, parallel algorithm for processing of GPR signals independent of MD signals, a GPR-only mode has been added that allows the operator to search for and detect completely non-metallic targets so that he may identify threats that cannot be detected with traditional metal detection or dual sensor technology.


In order to provide the highest level of operational security, the Mini-H provides a combined mode for missions involving completely unknown threats or targets. In this mode, both the Countermine and bulk explosives detection processes are operating simultaneously, ensuring that the operator can find all types of threats including both metallic and non-metallic.


L-3 CyTerra’s ground penetrating radar sensors, combined with advanced sensor processing, discrimination, and new bulk explosive detection algorithms have demonstrated the ability to detect low metal and even non-metallic threats.

New Versatility

By decoupling the GPR from the MD, the GPR is now capable of detecting and discriminating larger, deeply buried targets from shallow clutter and background. In addition, L-3 CyTerra’s new Continuous Wave Metal Detector (CWMD) technology has demonstrated better detection of both ferrous and non-ferrous metals, and a new wire detection capability. Increased Security: Based on a stepped frequency continuous wave (SFCW) technique rather than the more common pulsed approach, the Mini-H’s GPR is designed to be compatible with jammers currently deployed, likely reducing the need for operators in high-threat environments to drop electronic jammer defenses in order to operate their system.

New Design

Lightweight, Portable, Rugged Design and Construction
By leveraging ongoing improvements in integrated electronics, sensor design, and carbon fiber composite construction techniques, the Mini-H has significantly reduced size, weight and power, while increasing its structural integrity.

Simplified Operation, Faster Training
By providing simplified target detection tones and voice commands and taking advantage of the CWMD’s ability to characterize threats, L-3 CyTerra anticipates a decreased training burden resulting in heightened retention of training methodology.

Fast Reaction: Off-to-Operating “instantly”
L-3 CyTerra has updated its design to add a sleep mode after initial turn-on and ground calibration, and has added non-volatile storage of calibration data from most recent ground balance operations. As a result, the Mini-H can now be ready for use immediately.

Mini-H 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.
