Brief Analysis of Helicopter Collision Avoidance Radar Application Status and Technology Development Trend
The flight safety of helicopter is threatened by some static obstacles such as the terrain,chimneys and power lines,while the helicopter performing tasks of transportation,rescue and forest-firefighting at low altitudes.Airborne collision avoidance radar is an effective device for detecting these obstacles.In the complex environments of low altitude flight,the accurate location informa-tion of obstacles,such as distance and orientation,is provided rapidly by the collision avoidance radar for the helicopter to support pilots to dynamically plan and adjust flight routes to safely fly,which can improve the task implementation rate of the helicopter ef-ficiently and play an important part in elevating the level of helicopter's security.Based on the urgent demand of helicopter's flight safety,some main collision avoidance functions are discussed and the current application status of helicopter collision avoidance ra-dar is mentioned briefly in this paper.Then some technical design difficulties of helicopter collision avoidance radar are extracted based on engineering experience,and some forward looking thoughts of the collision avoidance technology are suggested.
