ABSTRACT:
A method of detecting the presence of a suspended filamentary object in view of a telemeter on an aircraft includes: i) calculating terrestrial coordinates of points corresponding to telemeter echoes, and selecting candidates; ii) searching a horizontal plane for straight line segments close to vertical projections of candidate points; and iii) searching each vertical plane containing one of the straight line segments for portions of catenaries close to candidate points. In step iii), for each considered vertical plane and each triplet of candidate points close to the considered vertical plane, calculating values of three parameters of a catenary containing the projections on the vertical plane of the three points of the considered triplet, and determining presence of at least one suspended filamentary object as a function of the distribution of values of catenary parameters calculated for all of the triplets of candidate points close to the vertical plane under consideration.
