| Abstract: | Effective situational awareness is very mportant when helicopter is taking-off or landing. To realize 3D image rendering of any stationary or dynamic obstacles, two technolgyes would solve, such as precise height measurement and cable detection. First, four solutions to realize precise measurement are presented in the paper, such as narrow beam, virtual aperture, height dimensional interference, and elevation super-resolution. Then,the electromagnetic scattering characteristics of high voltage transmission line are analysed. Lastly,field measurements of the power lines are given with a real aperture scanning-beam MMW radar, the collected data are analysed preliminarily. |
