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.
