A new, low-cost architecture of a 77 GHz automotive phase coded continuous wave radar sensor is proposed to provide accurate velocity and range measurements. Orthogonal signals provided by the multi-port module are combined into an intrinsic Doppler rejection technique, enabling accurate pulse compression. An increased range resolution is achieved using the pulse compression technique, while CW mode provides increased system solving capability in Doppler domain. The proposed system is an attractive solution for short-range millimeter-wave automotive sensors.
