Title: SYSTEM AND METHOD OF RADAR-BASED OBSTACLE AVOIDANCE FOR UNMANNED AERIAL VEHICLES
Abstract:
A method for radar-based object avoidance for a movable platform includes performing a plurality of "ping-pong" measurements to receive electromagnetic signals corresponding to an object and background clutters by a radar of the movable platform, and distinguishing the object from the background clutters. Each of the "ping-pong" measurements includes a first measurement and a second measurement. A first direction of the first measurement is different from a second direction of the second measurement.
