FIELD: invention refers to location technique. ^ SUBSTANCE: it may serve in quality of autonomous system of prevention of collisions securing safety of flight of helicopter. Achievable technical result is securing of circular survey for system of warning pilot of helicopter about presence of obstacles. Indicated result is secured due to definition of direction on obstacle and distance to obstacles with field of view with plane angle 360o with aid of arrangement having "k" identical receiving-transmitting modules including optical impulse transmitter with its own law of modulation switched to not scanning astigmatic optical system radiating in sector with plane angle 360o/k to receiving system containing "m" optical receivers each of which is switched to its own receiving not scanning astigmatic optical system receiving in sector with plane angle 360o/mk, sectors of receiving and transmitting optical systems are conjugated and form plane circular system of surveying with angle of 360o, outputs of optical receivers of modules are switched to inputs of system of processing of information and then into system of warning pilot which with aid of light and sound signals informs about presence, direction and distance to obstacle. ^ EFFECT: secures safety of flight of helicopters. ^ 2 dwg |
