Bengaluru: In a major development, the electronics and Radar Development Establishment (LRDE), a Bengaluru laboratory of Defense Research and Development Organization ,D R d o), has developed a major subsystem for space radar, which is not only used by the Indian Space Research Organization (ISRO).ISRO), but also for the military.
LRDE, which is involved in the development of space-borne imaging radars – mainly electronic radar subsystems and antenna Deployment Mechanism – Development of an Unfurlable Reflector Antenna (UFRA) for installation on satellites has been completed.
LRDE said that UFRA is one of the major sub-systems of radar, radar for space applications requires antennas to be compacted in volume during launch and deployed to the required size once the satellite reaches the required orbit.
“To meet this requirement, LRDE has developed the UFRA system consisting of a rim truss-based deployment mechanism, primary arm, reflector mesh, tension ties, mesh and motor. Through the diagonal members of the rim truss elements A cable is routed,” saying that one end of the cable is fixed and the other end is pulled by a motor.
“When the cable is pulled by a motor, the antenna made of metal mesh will be positioned into the desired shape. The UFRA was realized and deployment of the antenna to the required height was successfully achieved by an unflareable deployment mechanism. The design can be adapted to realize any size of UFRA.
Sources said the antenna could be a part of the space-based military radar on which the LRDE is working. “Specific details about the radar cannot be disclosed at this time, but the development of UFRA is an important milestone in the development of the radar,” said a source.
LRDE is a premier laboratory of DRDO which aims to design and develop state-of-the-art radar systems meeting the present and future requirements of the Tri Services, Para Military Forces, Intelligence and Strategic Missions. It is also tasked with setting up indigenous production capability through industry partnership so as to promote in-house research, involve academia and industry, besides building capacity towards creating a center of excellence in the field of radar technologies. Complete self-reliance can be achieved in radar.
