The SR75 is a compact 77GHz-band 4D high-resolution obstacle avoidance radar. It works by emitting a conical electromagnetic wave forward, detecting the reflections to determine whether there are obstacles ahead, and providing information such as the obstacle’s relative distance (length, width, height), angle, and speed. This radar is designed to give accurate feedback to drivers during low-speed forward or reverse movements. It has multiple transmit and receive antennas, featured with a measurement range of 0.1～40m. High sensitivity, stable performance, lightweight, and compact size, make it easy to integrate into various systems.It is particularly useful for low-speed vehicles, such as unmanned sweepers, environmental vehicles, driver training vehicles, and mining vehicles.
