摘要：
This paper presents a 2-dimensional radar imaging concept using a MIMO OFDM-based radar, which can also estimate velocity at the same time for automotive radar purpose at 24 GHz. The transmit OFDM signal is designed in such a way that the multiple transmitters will only radiate at the subcarriers unique to itself while preserving the total bandwidth and thus the range resolution. The virtual antenna array concept is utilized to widen the basis of the antenna array with the least possible transmit-receive elements. Using beamforming techniques at the receiver together with novel radar processing techniques, the range, Doppler, and azimuth information for an arbitrary number of objects (relative to the number of antenna elements used in the antenna array) can be estimated through a simultaneous transmission.
