Future cognitive radars will be threatened by jammers which employ cognitive capabilities to disrupt sensor capability. As cognitive capabilities are developed and deployed in packages of decreasing SWAP, script-based electronic protection systems relying heavily on a-priori information will be increasingly vulnerable. Cognitive electronic protection represents a capability that can restore the function of radar systems when faced with cognitive jammer threats. Vadum will develop the Electronic Warfare Advanced Capability Estimation (EW-ACE) suite of algorithms to provide electronic protection against cognitive jammer systems. The EW-ACE algorithms on Pulse Descriptor Words (PDWs) or similar high-level descriptions of received emissions and consist of association, characterization and inference algorithms. These algorithms are connected by a Jammer Behavior Object (JBO) which serves as a hierarchical data structure for storing information about both jammer observations (i.e., incoming PDWs) and inferences made during the execution of the algorithm. The JBO is a persistent data structure capturing a description of jammer behavior sufficient for EW-ACE to suggest electronic protection measures. After the execution of electronic protection measures, EW-ACE will monitor the response of the jammer and assess the effectiveness of the measures. The results of the assessment will be captured within the JBO for post-mission analysis.
