Abstract
A radar system may include an antenna structured to transmit a radar signal and receive reflected radar signals from targets and a processor operably connected to the antenna. The radar system may receive a first reflected signal, having a first arrival angle, at a first time. The radar system may receive a second reflected signal, having a second arrival angle at a second time. The second arrival angle may be equal to the first arrival angle plus an angle offset calculated based on a velocity hypothesis. The radar system may translate the first vector by applying the angle offset, thereby calculating a translated first vector. The radar system may calculate a beamforming spectrum based on the translated first vector and the second vector. The radar system may identify peaks in the beamforming spectrum to identify angular positions of multiple targets.
