A new phased MIMO radar partitioning schemes

The paper studies the performance of multiple input multiple output (MIMO) radar with collocated antennas called Phased MIMO radar. In this study, the transmit array will be partitioned into a number of sub-arrays that are allowed to overlap. Each sub-array transmits an orthogonal waveform to other sub-arrays. Compared to the phased-array radar, the use of MIMO radar with co-located antennas enables improving angular resolution, increasing the upper limit on the number of detectable targets, extending the array aperture. The tradeoff of this technique with different partitioning schemes is simulated using Matlab program environment for the corresponding beam pattern and signal-to-interference-plus-noise ratios (SINRs) expressions. The results demonstrate an important tradeoff performance between these different schemes.
