Tab. 1 – Rockfalls indicative rock size vs distance from the radar.
It must be stressed that these figures must be intended as pure indicative values; actual performance can greatly
differ, depending on many factors such as the radar-rock line of sight, rock material, number of rocks in the
avalanche, angle of fall and velocity, weather conditions etc.
Event detection performance of RockSpot are highly dependent on the
rock size and on their number (or on the size of the avalanche), distance,
fall angle, velocity, maximum emitted power, atmospheric conditions,
etc.
