SQUIRE

SQUIRE is a man-portable ground surveillance radar produced by Thales Nederland , the Hengelo-based radar specialist. The system entered service in the early 2000s and has since become one of the more widely fielded compact GSRs in NATO, used to watch the perimeters of forward operating bases, fixed installations, and national borders. Its purpose is straightforward: give a small detachment of soldiers a reliable picture of what is moving in the kilometres around them, day or night, in fog, smoke, or rain.

The radar operates in J-band and is built around a tripod-mounted antenna that two operators can set up in a few minutes. Maximum detection range is published at roughly 48 kilometres against vehicles, with walking personnel still picked up at substantially shorter ranges in good conditions. A Doppler-based signal processor automatically classifies returns as walking personnel, wheeled or tracked vehicles, or low-flying helicopters, sparing the operator the workload of interpreting raw plots. The unit runs on rechargeable batteries for several hours and can be driven from a ruggedised laptop cabled to the antenna or, in later configurations, from a remote position via radio link, keeping the operator out of the line of sight of whatever the radar is watching.

Operators include the Netherlands, Germany, Norway, Sweden, and Estonia, along with a number of other NATO and partner militaries that have bought the system in smaller batches over the years. The Dutch Army and the German Bundeswehr both deployed SQUIRE in Afghanistan, where it served as a standard short-to-medium-range force-protection radar around ISAF bases, flagging movement on approach routes and cueing cameras and patrols. Estonia has fielded it along its eastern border, where the role shifted from expeditionary base protection to keeping watch on Russian-side activity in the years after 2014. The radar’s combat record across two decades of NATO operations is part of why it has kept selling.

Thales has refreshed the family in successive production blocks, adding improved classification algorithms, tighter integration with battle-management systems, and software updates aimed at lowering false-alarm rates against wildlife and weather clutter. SQUIRE sits in a competitive niche populated by similar man-portable Doppler GSRs from Israeli, Swedish, and American makers; its draw has been a balance of weight, detection range, and a procurement footprint that suits both expeditionary forces and quiet border posts where the radar may run for years on end.
