Abstract	Controlling the polarisation states of the transmitter and the receiver enables improving the performance of radar systems, especially for mainlobe interference suppression applications. In this study, the authors consider the design of optimal polarisations at both of the radar transmitter and receiver for mainlobe interference suppression. They propose the polarimetric multiple-input–multiple-output (MIMO) radar which combines the advantages of MIMO systems with the advantages offered by optimally choosing the transmitter polarisation or the receiver polarisation to achieve a better anti-jamming performance. The polarisation diversity is employed in the transmit array and the receive array. The interferences can be suppressed by the oblique projection filter. Based on the output signal-to-interference-plus-noise ratio analysis, the optimal transmitter polarisation and the receiver polarisation can be obtained. Simulation results demonstrate that interference can be effectively suppressed with the radar configuration, and better interference suppression performance can be achieved with the optimal transmitter polarisation and receiver polarisation.
