In order to improve the positioning and ranging capabilities of the robot, a method of processing information based on robot radar positioning is proposed. The radar scanning is used to collect the positioning signal of the robot. The phase difference method is used to estimate the target position of the robot from the radar signal of the simulated target echo. A parameterized dual-frequency mode generator is designed to achieve accurate positioning of the robot. The basic models of single-frequency and dual-frequency mode objectives are proposed, and the initial phase of the modulation generated by the distance is obtained. The dual-frequency mode spectrum obtained from the actual data and the parameters such as the calculated distance, velocity, and acceleration are calculated and analyzed. Simulation results show that this method can improve the accuracy of robot positioning. The signal-to-noise of the radar signal output is relatively high, which indicates that the robot positioning has strong anti-interference ability, which improves the positioning accuracy of the robot.
