Hybrid diversity strategy using MIMO radar for target tracking

For the development of radar systems with enhanced performance in target detecting and tracking abilities, various research groups have been investigating multiple input multiple output (MIMO) based radar systems. They have shown that MIMO radars perform better compared to conventional systems like bistatic or even SIMO radars. Especially MIMO capitalizes several diversity parameters inherent to its design to give higher resolution in both range and range rate. Several papers address these diversities. The current work aims at parameterizing these diversities especially spatial, waveform and frequency diversities and hence designing a system which employees a the resultant diversity constraints on the transmitter architecture and on the type and properties of transmit signals. As done in conventional system analysis, here also the formulation of ambiguity function is addressed and in the process a new tool called ambiguity function pair is developed. It has been shown with example evaluations that this ambiguity function pair is more mature in analyzing and tracking targets with systems employing diversity constraints. In the process of evaluation a new strategy with adaptive framework for tracking targets and getting higher range resolution and is addressed.
