CPC G01S 7/36 (2013.01) [G01S 7/021 (2013.01)] | 18 Claims |
1. An apparatus for protecting an asset from an imminent radar threat that is emitting a hostile radio frequency (RF) waveform and poses an imminent threat to the asset, the apparatus comprising:
an antenna configured to receive the hostile RF waveform;
a receiver configured to amplify and digitize the hostile RF waveform;
a signal analyzer configured to isolate the hostile RF waveform;
a countermeasure library containing known countermeasures that are pre-verified as effective against associated known radar threats; and
a Cognitive Electronic Warfare System (CEW) configured to:
A) select a defined countermeasure from the countermeasure library;
B) populate the selected defined countermeasure with an initial parameter set comprising at least one parameter to create a candidate countermeasure;
C) apply the candidate countermeasure against the imminent radar threat;
D) assess an effectiveness of the applied countermeasure against the imminent radar threat;
E) if defined effectiveness criteria are not met by the applied countermeasure, vary at least one of the parameters, wherein varying the at least one of the parameters includes correlating changes in the at least one of the parameters with resultant changes in the RF waveforms emitted by the imminent radar threat;
F) repeat steps C) through E) until the defined effectiveness criteria are met, or until the assessed effectiveness is maximized; and
G) if the defined effectiveness criteria are met, designate the candidate countermeasure as an effective countermeasure against the imminent radar threat.
