Thank you so much for posting that article. Very interesting reading. I hope some people have read this instead of trying to find information in the Croation Times!
I hope they have overcome the difficulties with using a helicopter. I am sure they have addressed them because it would be pretty stupid to do a demo in an untested system.
AIRSHIP
The airship, an American Blimp Corporation A-60, was provided by the Lightship Group. The airship is a low vibration platform to carry the wideband radar and electro-optical payloads, overcoming the limitations of other air platforms such as the helicopter. The airship has a number of advantages. It operates at slow speeds and low levels for long periods of time and also has the capability to remain nearly stationary when required. There is no propeller blade downwash, which reduces the probability of an accidental mine detonation. In areas where a helicopter may be seen as a threat, the airship provides a high public awareness and non-threatening airborne platform for the aircrew to safely overfly the area and carry out the mine survey operations.
The system's capability to detect and image buried and surface laid mines and mined areas has been demonstrated at Qinetiq's Waterloo Lines test site at Pershore in UK and also in Kosovo, showing that the system will be able to map suspected and confirmed mine areas very quickly, at more than 100 square metres per second
Could Croatia be the government they are dealing with for contracts and this demo is to satisfy them.
