Device for obstacle detection for pilots of low flying aircrafts.

摘要

The arrangement operating in accordance with the laser radar principle comprises a pulsed laser range finder (LRF) for scanning a predetermined field of vision and for the pictorial representation of the contour of the perceived obstacle for the pilot on a display, an array of semiconductor laser diodes or, respectively, of receiving detectors being provided in each case as transmitter and as receiver of the LRF and the field of vision being scanned by means of a meshed- grid-shaped pattern. These measures minimise the expenditure for the individual components of the arrangement and achieve a simple compact structure. The arrangement is suitable for obstacle warning for aircraft, particularly for low-flying helicopters.
