Coloured transmission based on multicarrier phase coded signals in MIMO radar

In radar processing, coloured transmission aims at improving the detection of targets that appear as fast as they disappear. It consists in simultaneously transmitting different waveforms using a wide beam. To differentiate the transmitted waveforms, various orthogonal coding schemes such as phase and frequency coding have been considered. In this paper, we suggest using in the MIMO radar case the so-called multicarrier phase coded signals (MCPC) initially introduced in SISO radar processing. This approach has the advantage of having better performances than phase coding based schemes. In addition, it has a lower computational cost than the frequency coding system.
