Airborne Oil Spill Surveillance Systems in Sweden

摘要

Two different oil spill surveillance systems are described. These systems are presently installed in two Cessna 337 aircraft. One of the systems is based on a side looking airborne radar (SLAR) and the other on a Daedalus IR/UV-line scanner. In both systems imagery generated from the sensors is presented in real-time on a TV-monitor to the operator/co-pilot in the aircraft. The SLAR system generates black-and-white imagery whereas the IR/UV-scanner system uses false color coding for image enhancement. The IR/UV-scanner system also has capabilities of recording unprocessed data on tape, polaroid photographing of displayed images, and near real-time image transmission down to ships via a TV video to Xerox telecopier interface and a voice channel link. The technical evaluation and field testing of the two systems is summarized. Most of the tests were carried out in the Baltic Sea and included oil spill detection, cleanup surveillance, ice reconnaissance, monitoring of fishing activities, and search and rescue operations.
