摘要

当前的汽车雷达传感器采用多输入多输出的方式来提高角度分辨率。通常应用的时分复用方案的缺点是与发射机数量成比例的明确多普勒速度降低。在本文中，提出了一种信号处理方案，以获得与单输入多输出情况下相同的无二义多普勒。仿真和测量结果表明，信号处理可以提高无二义多普勒速度估计。

Enhancement of Doppler Unambiguity for Chirp-Sequence Modulated TDM-MIMO Radars

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.
