To deal with the problem of helicopter collision avoidance,the target detection and recognition technology of air power lines based on millimeter wave radar is studied.The algorithm for target data processing based on Hough transform is given.Compared with optical equipment,the millimeter wave radar provides all-weather and continual target detection and identification for helicopters.The millimeter wave radar equipment is used to record the power line echo.The echo characteristic of power lines is analyzed.First,movement compensation is carried out.Then,Hough transform is used to detect lines.Finally,the point and line targets are processed respectively.The experiment result shows that the power line is detected effectively with the algorithm,so it can be used in helicopter collision avoidance.
