HETS Helicopter Obstacle Detection System

Helicopter platforms are widely used in adverse weather and low-altitude/high-speed conditions for mission success. At these circumstances, detection of the vertical and horizontal obstacles and alerting the pilot in a timely-manner is an important safety issue. HETS is an equipment which uses 1550 nm wavelength fiber-laser, which detects obstacles such as wires, poles, trees etc. The system detects the obstacles and gives necessary alerts to the pilots with aural and visual means.

System is operational with 30*40 degrees Field-of-View, and scans in 2 Hz for detecting vertical and horizontal obstacles upto 5 mm diameter. Total instrumental range is 1500 m. With the LIDAR technology, accurate signal processing and user-friendly visualization characteristics, HETS alerts the pilot on-time against obstacles.
