Saab Sensis has announced that it has successfully completed Site Acceptance Testing (SAT) of the hardware modernisation programme currently being carried out on four Hughes Air Defense Radars (HADR) for the German Air Force (Luftwaffe). The radars are being modernised and upgraded to extend their service life, reduce and simplify maintenance and improve detection performance as a less costly, lower risk alternative to fielding new radars.
The company has now deployed a new Commercial-Off-The-Shelf (COTS) receiver/exciter, radar signal processor, radar data processor and display function in one cabinet, marking an important milestone in the upgrade programme’s progress.
The HADR is a ground-based air surveillance defense radar that was first deployed in Germany over thirty years ago. Today, obsolete components make maintenance costly, difficult and time consuming while the technology and computer algorithms lack the capability to accurately detect and track contemporary targets.
The Saab Sensis HADR modernisation programme maintains the existing operational and performance requirements and was conducted while the radars remained in service. The COTS solution provides more reliable position estimates in clutter, increases detection and reduces gaps and blind spots. In addition, the upgrade reduced the number of Line Replacement Units (LRUs) and eliminates the need for tuning and calibration.
Erik Smith, general manager of Defense Products and Programs at Saab Sensis, said: ‘The Saab Sensis COTS radar modernisation approach is a proven, effective means of extending the service life of existing air surveillance radars in a lower risk, lower cost manner than fielding a new radar. The result is an improved radar that is ready to detect today’s airborne threats without the need to retrain radar operators.’
The airborne three-domain, the two ground-based and the ¼ ATR OpenVPX-based cross-domain systems were engineered to provide real-time security across multi-domain operations.
DARPA’s Mission-Integrated Network Control (MINC) programme was set up to develop an autonomous tactical network and enable critical data flow in contested environments.
Why space is an essential part of modern military capabilities
Defence-secure mixed reality headsets can save hours, or even weeks, of travel time to fix defunct equipment or get subject experts effectively “on-site” where they are needed.
The Joint Counter Radio-Controlled Improvised Explosive Device Electronic Warfare (JCREW) counter-improvised explosive device (C-IED) and Drone Restricted Access Using Known Electromagnetic Warfare (DRAKE) counter-UAS (CUAS) systems are mounted and dismounted RF jammers.
Adarga’s Vantage information analysis tool is in service with the UK MoD and individual UK forces. It builds on the company’s Knowledge Platform which processes, organises and analyses open source material, as well as information held by the user’s military, security and intelligence services.
