Probing signal design for MIMO radar: A Riemannian distance approach

We consider the problem of designing probing signals for a Multi-Input Multi-Output (MIMO) radar. The goal is to design a signal vector with a desired covariance while ensuring the side-lobes of the ambiguity functions are small. We will also consider cases in which a bandwidth constraint is placed on the signal. Since covariance matrices are structurally constrained, they form a manifold in the signal space. Hence, we argue that the difference …
