A High Angular Resolution Transceivers Cascaded Automotive Front Radar with Novel Antennas

With 2 transceivers cascaded and multiple-input and multiple-output radar technology used, the angle detection resolution for azimuth direction can reach better than 1.4 degrees, which will bring better angular resolution than the current automotive front radar. What’s more, a new array is proposed for automotive front radar application. According to simulation results,the radiation patterns of the proposed antenna can cover medium and long range field of view.
