[IEEE 2018 Second International Conference on Inventive Communication and Computational Technologies (ICICCT) - Coimbatore (2018.4.20-2018.4.21)] 2018 Second International Conference on Inventive Communication and Computational Technologies (ICICCT) - Beamforming Using Phased Coprime MIMO Radar

摘要： This paper proposes a new method of beamforming for colocated MIMO radar with the coprime arrays. The proposed method splits the transmitting array into multiple overlapped subarrays and then transmits a coherent signal through each subarray, to achieve a maximum power in the desired direction. However, the signals from distinct subarrays are independent to preserve the diversity bene?t of the MIMO radar. Thus, the proposed method exploits the advantages of both phased array and MIMO radars as well as the coprime arrays. Simulation results are presented to signify the beampattern and the signal to interference plus noise ratio performance of the proposed method and to compare with the earlier methods such as phased array radar, MIMO radar and the coprime MIMO radar.
