초록

A helicopter hazardous ground object warning system has a horizontally rotating beam from a laser rangefinder which detects and measures the distance to ground objects which may present a hazard to a helicopter during hover, takeoff and landing. The rotating laser beam from the rangefinder is positioned on the fuselage of a helicopter to create a quasi-horizontal (planar) scan pattern parallel to the earth\s surface. The maximum and minimum ranges which can be measured by the rangefinder to objects and to ground personnel are preset. The minimum range ca...
