Multiple Input Multiple Output (MIMO) antenna systems have shown a great potential for wireless communication. These systems support high capacity, increased diversity and interference suppression. Recently it has been proposed MIMO constellations for Radar. MIMO Radar is not only a new research field, but also a very promising approach in terms of overcoming Radar Cross Section (RCS) fluctuations with diversity. This thesis explores the potential of coding schemes for MIMO Radar.

The ambiguity functions measures related to MIMO Radar are used to evaluate how much diversity gain can be coherently achieved with certain coding schemes. The results of this analysis show that the cross correlation between the signals from different transmitters hinders achieving the full diversity gain. The code length of the used Gold codes is an important factor for this effect.

However, in this thesis a coding scheme related to the Alamouti scheme in Communication is presented, this scheme under some constraints is capable of maintaining orthogonality between the signals from different transmitters and therefore cancels the mutual interference among those signals.

In general, MIMO radar is a novel and ingenious approach to improve radar performance which needs to be analyzed and developed. This thesis is the first work exploring the coding schemes and the related aspects for MIMO Radar.
