Products and Services

Silentium’s ‘MAVERICK’ passive radars bring a new dimension to the world of surveillance and situational awareness. From lightweight, soldier-portable systems for land tactical surveillance to fixed and deployable systems for strategic surveillance of sea, air, and space, our passive radars provide cost-effective protection without compromise, and an undeniable advantage over traditional radar systems – the ability to see without being seen.

Modular, scalable, and quick to deploy, MAVERICK passive radars easily adapt to support mission requirements and allow Defence to simultaneously detect and track a broad range of targets from low, slow-moving objects such as drones, to high, fast-moving jets, vehicles and space-debris and satellites in low-earth-orbit. Unlike traditional radar, our systems don’t emit, so they can’t be detected, don’t create a radiation hazard and don’t require spectrum allocation to operate making them quicker, safer and more cost effective to deploy.
