A method and device is disclosed for increasing the hit probability of guided missiles exposed to jamming by double or multiple targets. In particular, the missiles are guided by the proportional navigation principle and have a follow-up target-seeking head. With the addition of a plurality of tracking filters, means for performing data analysis and means for performing data control to a conventional missile guidance system, signals from the target-seeking head or the missile may be analyzed to provide recognition of double or multiple target situations. Once recognition of the double or multiple target situation is made, the flow of data for controlling the guidance and target-seeking head follow is corrected to keep the missile permanently on the target.

A method for increasing the hit probability of missiles which are subject to being jammed by double or multiple targets and which missiles are guided by means of proportional navigation and have a target-seeking head capable of following up comprising the steps of: assigning measured values siM of a first target recognized by the target-seeking head of the missile to a first filter, F1, for target track formation as well as for guidance and target-seeking head follow-up; separating the first filter from the measured values siM of the target-seeking head if the measured values result in a determination that there is movement of the line of sight of the missile, which measured values must have been caused by a target maneuver which is outside of predetermined limits because of the maneuverability of airborne targets; continuing to form by extrapolation in said first filter the probable target track after said filter has been separated and influencing the guidance of said missile and target-seeking head with said probable target track; supplying, after separation of said first filter, measured values of target track information from a second target to a second filter F2; separating the second filter and again providing the first filter with measured values by the target-seeking head when the measured values are recognized to belong to the target track processed by the first filter; and recognizing measured values belonging to no target track and not processing such measured values.
