An infra red thermal imaging
surveillance system that is used by close air defence units, to detect
hostile aircraft and helicopter targets and directs weapon systems
into the target area.
The air defence missile operators can be alerted to up to four targets
in a priority order. This passive system which is built by Thorn EMI
has an all weather, day and night capability.
The Air Defence Alerting device is
a passive air defence alerter designed to work in conjunction with the
HVM missile system. Operating as an infra red search and tracking
system in the 8 - 14 micron waveband, the alerter is designed to
operate against low and fast moving fixed wing aircraft, as well as
the latest generation of attack helicopters. The alerter can be ground
mounted to support shoulder launched / LML HVM or vehicle mounted on
the Stormer HVM vehicle.
