A system includes a threat warning system and a countermeasure system. The threat warning system generates threat data that includes at least a threat coordinate value. The countermeasure system includes a wide-angle laser beam director and the infrared counter measure system that is configured to receive the threat data including the threat coordinate value from the threat warning system and causes the beam director to direct a divergent laser beam based on the threat coordinate value and cause the beam director to vary an angle of the cone based on an aircraft signature perceived by a threat.

System and method for a directable countermeasure with divergent laser

A system includes a threat warning system and an countermeasure system. The threat warning system generates threat data that includes at least a threat coordinate value. The countermeasure system includes a wide-angle laser beam director and the infrared counter measure system receives the threat data including the threat coordinate value from the threat warning system and causes the beam director to direct a divergent laser beam based on the threat coordinate value.

Techniques are disclosed for producing and/or optimizing jamming codes for use in directional infrared countermeasures (DIRCM) systems. In some embodiments, Fourier analysis may be implemented to produce jamming codes which more efficiently (e.g., time efficient, power efficient) and/or more reliably (e.g., no frequency gaps) achieve optical break-lock (OBL) of infrared (IR)-seeking missiles/threats over a broad range of frequencies (e.g., short-wavelength IR, mid-wavelength IR), as compared to heritage jamming code methodologies. Some embodiments may be implemented in military/defense applications (e.g., protection of military/tactical aircraft or other vehicles); some other embodiments may be implemented in non-military/commercial applications (e.g., protection of domestic, civilian, and/or commercial aircraft or other vehicles). Some embodiments may be implemented to protect against IR-seeking air-to-air missiles (AAMs), surface-to-air missiles (SAMs), and/or man-portable air-defense systems (MANPADS/MPADS). Numerous configurations and variations will be apparent in light of this disclosure.
