Swedish Air Force: High-altitude camera installed in aircraft. 
Most of the aircraft used in the experiment plus one Vertol heli- 
copter were based in Luled at the Bay of Bothnia, 
Swedish Administration of Shipping and Navigation: Modern ice- 
breaker equipped with helicopter, hydrocopter etc., 
Swedish Meteorological and Hydrological Institute (SMHI): 
Extensive field measurements. Represented in the project managing 
group, 
Saab-Scania (Sweden): Radar altimeter installed in a helicopter, 
and Swedish Space Corporation: Coordination and management of the 
project. 
SEA ICE 75 was coordinated and managed by a project-managing group 
consisting of: Project leader (Cla2s Pilo, Swedish Space Corporation), 
Scientific leader (Thomas Thompson, SMHI), and Technical leader 
(Ake Blomquist, FOA). 
The head of the Ice-breaking Service of the Swedish Administration 
of Shipping and Navigation, Captain Agne Christenson, Royal Swedish 
Navy, closely followed the project. 
The project managing group was based on the ice-breaker TOR during 
the experiment and worked in close contact with the captain of the 
ice-breaker, Commander Yngve Nilsson. 
The reports were published in the series of research reports issued 
by the Swedish-Finnish Board for Winter Navigation Research. 
5.1 Sensors 
One of the main features of a sensor intended for ice mapping is 
its mapping capacity. The highest mapping capacities were obtained 
by radar sensors, such as SLAR, FLAR, and ODAR. 
5.1.1 SLAR 
The real aperture SLAR (Side-Looking Airborne Radar) used in SEA 
ICE 75 was not designed for ice mapping and the instrument setting
