Patent number: 11733349Abstract: A method of selecting and optimizing a countermeasure for application against a novel, ambiguous, or unresponsive radar threat includes selecting a candidate countermeasure and an initial parameter set and varying at least one of the parameters while the effectiveness of the candidate countermeasure against the radar threat is assessed, for example by a human observer. Embodiments include repeating the process with additional candidate countermeasures. For an unresponsive radar threat, a previously effective countermeasure can be selected as the candidate countermeasure. For an ambiguous radar threat, at least one countermeasure previously verified as effective against a partially matching known threat can be selected as the candidate countermeasure.

Publication number: 20230244824Abstract: An on-chip firewall circuit for providing secure on-chip communication is disclosed. The firewall circuit includes a configurable table of port IDs along with a configurable setting for each port ID to either provide the corresponding port ID with open access to the components of a secure enclave (SE) module or restricted access.
