Optical-theorem-aided data-driven radar imaging

Change detection algorithms for unknown multipath environments are derived that are based on the classical optical theorem of scattering theory. The methods are data-driven and prior knowledge of the scene is not required. They are presented in a framework suitable for implementation with ad hoc multistatic sensor arrays. Complementary realizations are derived that enable, in practice, the continuous dynamic reconfiguration of the network for resilient radar operation in contested environments.
