Meteksan Defence will be exhibiting its active laser-based Helicopter Obstacle Detection System (HETS) for the first time at the IDEF’21 exhibition to be held on 17-20 August.
The company developed the system, within the scope of a contract signed in 2019 with the Presidency of Defence Industries.
HETS was developed with a fiber laser that has a wavelength of 1,550 nm. It has the capability of detecting human-made structures such as buildings, towers, poles, power lines, and natural obstacles such as trees, forests, and hills, and provides audible and visual warnings to pilots. Supporting different interfaces for easy integration into different helicopters, the system differs from its competitors in the world with its low power consumption and low weight.
HETS can detect horizontal and vertical obstacles including 5mm power lines by scanning twice a second in its 30*40 degrees field of view and has an instrumental range of 1,500 m.
Helicopter platforms are widely used in adverse weather as well as low-altitude and high-speed conditions for mission success. Therefore, every year, lots of helicopter accidents occur by colliding with obstacles around the world. In order to prevent accidents, it is very important to detect obstacles during flight and to provide warnings on time.
