Turkish firm Meteksan said it will display laser-based Helicopter Obstacle Detection System (HETS) for the first time at IDEF-2021 exhibition scheduled to take place in Istanbul fro, 17-20 August, 2021.
The HETS was developed within the scope of the contract signed between Turkey’s Presidency of Defense Industries (SSB) and the company in 2021.
The system consists of a fiber laser that has a wavelength of 1550 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/visual warnings to pilots.
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 1500 m. It warns the pilot against obstacles at appropriate times with LIDAR technology, high precision signal processing, and user-friendly visual creation capability. Also, HETS can produce synthetic sound and tones in addition to a visual warning. The system supports MIL-STD- 1553, RS-422, and ARINC-429 interfaces for use in integrated structures as well as producing video for MFDs.
