Broadband Array Time Reversal Method for Jamming with Protective Constraints

This paper aims to design a jamming signal for a broadband array in the presence of known stationary users. If the transmit paths to the sources are known, we can adopt MIMO downlink schemes which can be extended to the broadband case using an analytic singular value decomposition of the different transmission matrices. If the transmit paths to the sources to the be jammed are not known but the source have previously been detected from their emissions, under the assumption of channel reciprocity we utilise a time reversal technique. We compare its performance and robustness to the case of channel knowledge in simulations.
