当前的汽车雷达传感器使用多输入多输出方法来增强角分辨率。经常应用的时分复用方案具有与发射机的数量成比例的降低的明确的多普勒速度的缺点。在本文中，信号处理方案提出了恢复相同的明确的多普勒在单输入多输出的情况下，只有一个发射天线。仿真和测量结果证明，信号处理可以增强无模糊的多普勒速度估计。
Current automotive radar sensors enhance the angular resolution using a multiple-input multiple-output approach. The often applied time-division multiplexing scheme has the drawback of a reduced unambiguous Doppler velocity proportional to the number of transmitters. In this paper, a signal processing scheme is proposed to regain the same unambiguous Doppler as in the single-input multiple-output case with only one transmit antenna. Simulation and measurement results are shown to prove that the signal processing leads to an enhanced unambiguous Doppler velocity estimation.
