Abstract

A sensor has been designed to provide real-time detection and recognition of 3 mm wires at range of 300 meters during nighttime helicopter flight operations. An Army-sponsored program to demonstrate such automatic wire detection and warning for Nap-of-the-Earth (NOE) helicopter missions is currently in progress. Wire or wirelike objects are electro-optically detected and then recognized by a pattern recognition technique. The recognition algorithm is accomplished within 50 msec of the first wire detection indication. A flyable exploratory development wire obstacle warning system model, consisting of a scanning laser transmitter, electro-optical receiver, real-time processor, and display unit is described.
