The COBRA antenna can be mechanically rotated in azimuth by ± 90 degrees with respect to
the longitudinal axis of the vehicle and in elevation from –5° to + 35° relative to a plane perpendicular to the shelter bottom surface .
COBRA can be brought into action in less than 15 minutes. The encamp time includes the time
taken to load the Digital Terrain Map (DTM) from hard disk, and to complete COBRA Initialisation
and mission parameter definition. It is possible to come out of action within 5 minutes.
Location of Jammers
During passive non-transmitting periods, COBRA provides azimuth and elevation direction for
jammers within the passive observation search sector using the antenna mainlobe; in addition,
information on jamming mode, jamming strength, presence of mainlobe or sidelobe jamming,
and jammed frequency channels is gathered and stored.
During radar transmissions a second means of gathering information on non-responsive and
responsive and moving jammer platforms is provided.
