WebJan 24, 2024 · Imaging radar, also referred to as high-definition or high-resolution radar, is designed to bridge some of the gap between current-generation radar and lidar – while retaining the traditional advantages of the radio frequency-based sensors. Like lidar, radar is an active sensor that emits a signal and listens for reflections. Weban imaging radar are in the range 10 to 200 MHz. At the Earth's surface, the energy in the radar pulse is scattered in all directions, with some reflected back toward the antenna. Thisbackscatter returns to the radar as a weaker radar echo and is received by the antenna in a specific polarization
