PCT No. PCT/IT91/00072 Sec. 371 Date Jul. 7, 1992 Sec. 102(e) Date Jul. 7, 1992 PCT Filed Sep. 5, 1991 PCT Pub. No. WO92/04643 PCT Pub. Date Mar. 19, 1992.Detector of suspended cables specially suited for avionic applications formed mainly by a scanning system (S) provided with a noise generator (1) and scan concentrator (3); by a Lidar system (L) and an extractor system (E). The latter is composed of a background filter (7) and a chain extractor (8). This detector, if included in the on board instrumentation of light aircrafts and helicopters, is in condition of supplying the pilot with a warning signal if suspended cables are detected in the flight path during low altitude flights. The instrument gives the cable position and allows the selection of the right corrective move. The invention finds its most convenient application in the flight safety field while that of the avionic optical radars is the specific technical field of this device.
