METHOD FOR PREVENTION OF HELICOPTER COLLISION WITH HIGH-VOLTAGE POWER TRANSMISSION LINES Russian patent published in 2010 - IPC G01S13/93 G08G5/04 

FIELD: radio engineering.

SUBSTANCE: method consists in reception of electromagnetic oscillations reflected from supports of power transmission line in the range of radio waves by the first and second direction finders arranged in helicopter at distance B along front from each other. Each of direction finders scans space along helicopter flight, besides the first direction finder does scanning counterclockwise, and the second one - clockwise, observed bearings are identified for each of two supports of power transmission line by each direction finder, besides α₁ and α₂ -observed bearings are identified with the first direction finder of the first and second support of power transmission line, and β₁ and β₂ - observed bearings - by the second direction finder of the first and second support of power transmission line relative to construction line of helicopter, distance is determined to wires of power transmission lines along with direction of helicopter construction line with the help of according calculation formula, and based on distance value, decision is made on correction of helicopter flight direction adjustment.

EFFECT: increased accuracy of determining shortest permissible distance between helicopter and power transmission line.
