DEVICE FOR PREVENTION OF HELICOPTER COLLISION WIT OBSTACLES Russian patent published in 2009 - IPC G01S13/93 

FIELD: transportation.

SUBSTANCE: directions to obstacle and distance to it are defined in field of view with flat angle of 360° with the help of device, which comprises "k" identical transceiver modules, which include optical receiver, inlet of which is connected to receiving non-scanning astigmatic optical system, which receives in sector with flat angle 360°/k and low vertical angle, transmitting system of each module comprises modulator with its modulation law, which, through control unit, generates signals "m" of optical pulse transmitters, every of which is connected to its transmitting non-scanning astigmatic optical system, which radiates in sector with flat angle 360/mk, sectors of transmitting and receiving optical systems inside and between modules are coupled and create a flat circular system of view with angle of 360°. Outlets of optical receivers of modules are connected to "k" inlets of information processing system, to which information is also supplied from "mxk" inlets of optical module transmitters control. Outlet of information processing system is connected to system of pilot warning, which, with the help of light and sound alarms, informs about availability, direction and distance to obstacle.

EFFECT: provision of circular view for system of helicopter pilot warning about availability of obstacles.
