| Abstract: | Anti-collision radar plays an irreplaceable role in the environment identification of smart cars, and an anti-collision radar based on AWR1642 has been designed, The distance and orientation information of obstacles are obtained by means of FFT algorithm in time domain and DBF algorithm in space domain for the echo signal received by 4-channel receiver. According to the technical parameters provided by AWR1642, the main technical indexes of the system are proposed and proved. The experimental results show that the system can meet the accuracy requirements of ranging and angle measurement. |
