1. A computer readable storage medium, tangibly embodying a program of instructions executable by the computer for generating at least one optical break lock code segment for jamming a first IR radiation seeking threat, the program of instructions, when executing, performing the following steps: generating a set of telescope spin frequency weighting values for the first IR seeking threat based at least in part on telescope spin frequency variation data for the first IR seeking threat and jam power data for the first IR seeking threat; and generating an optical break lock code segment for the first IR seeking threat based at least in part on the set of telescope spin frequency weighting values, wherein the optical break lock code segment is generated such that: (a) the optical break lock code segment comprises, based at least in part on the set of telescope spin frequency weighting values, a plurality of frequencies associated with the first IR seeking threat; and (b) a power of at least a first one of the plurality of frequencies associated with the first IR seeking threat is weighted in the optical break lock code segment, based at least in part on the set of telescope spin frequency weighting values, to be different from a power of at least a second one of the plurality of frequencies associated with the first IR seeking threat.
