Principle of Operation
The radar consists of two horn antennas located above the fairing, which provide continuous monitoring of the space between the helicopter and the ground surface.Due to the features of the 3-mm wave range implemented in the radar design, the reflected radar signal received by the antennas after processing allows detecting and determining with high accuracy the coordinates of both elements of the ground surface and interfering (dangerous) objects, including small-sized ones, which is unattainable in other wave ranges. Information about the presence of dangerous objects and their position, as well as the distance to the ground surface and its position relative to the axes of the helicopter can be provided to the pilot (navigator) in a convenient form.
This ensures the safety of takeoff and landing in restricted optical visibility, especially in particularly dangerous conditions of sand, dust, water spray, snowstorms, preventing collisions with interfering and dangerous objects, monitoring the attitude relative to the ground surface, ensuring landing at a given point.
Benefits
- Low overall dimensions
- Easy installation
- All-weather and all-day operation
- Landing support in sand, dust, water spray, snow storm conditions
- Detection of obstacles, small interfering objects against the background of the underlying surface
Scope
-
Newly developed and modernized helicopters of all classes, sizes and purposes (civil, military and special): attack, intelligence, rescue, transport, ambulance, fire, patrol and monitoring and others, land and ship-based ones.
