Abstract
A method and system for detecting wire in a terrain avoidance, terrain following, or a terrain obstacle system. Radiant energy pulses orthogonally polarized are alternately transmitted. Selected dimensions of a full scattering matrix of adjacent reflected pulses for a particular range are collected and combined to form a null matrix. A null matrix with the two reflected pulses being within a predetermined distance from one another is detected as a wire.
