Method of Applying Soft-Kill Deployment, a Soft-Kill Deployment System and a Computer Program Product

A method of applying soft-kill deployment to mislead an incoming missile directed to a mother platform, the method comprising the steps of:

• predicting a number of miss distances associated with corresponding particular decoy launch parameter sets,
• selecting a decoy parameter set having an optimal predicted miss distance;
• and
• transmitting the selected decoy parameter set to a launch unit for launching the decoy;
• wherein the predicting step includes the use of an adjoint algorithm, wherein the method further comprises the step of computing uncertainty data associated with a predicted miss distance, and wherein, in the step of selecting a decoy parameter set, the computed uncertainty data is taken into account,
• further comprising a step of validating the effect of the launched decoy, the validation step comprising the substeps of:
• predicting a zero-effort miss distance, under platform lock on condition and/or decoy lock on condition;
• measuring incoming missile data;
• comparing the measured data with the predicted zero-effort miss distance or distances;
• deducing, from the comparison results, on which entity the incoming missile is locked.
