The invention proposes to provide distraction spoofing even on modern infrared, radar and dual-mode guided missiles (4) by production of a decoy chain (20). The chain (20) is formed by a plurality of apparent targets which are switched successively, for example by firing of individual chaff submunitions (2.1-2.5). The deployment takes place before or during the search phase of the missile and can in this case, for example, be carried out using the reverse walk-off principle or at the same time simultaneously or successively and in the form of a pattern. This ensures that the decoys (2.1-2.5) act initially in the greatest selected range zone away from the target (3). The spoofing chain (20) created in this way results in the missile (4) having to carry out a series of time-consuming analysis processes on its way to the target (3).

1. A method for protecting an object from infrared-guided, radar-guided, and dual-mode guided missiles by way of submunitions, which, as decoys, form a decoy chain, and are deployed by a munition, the method comprising the step of deploying the decoys of the decoy chain in a manner so that effects of the decoys occur at respective predeterminable distances from the object and counteract the missile at different ranges from the object. 2. The method in accordance with claim 1, including simultaneously deploying the decoys. 3. The method in accordance with claim 1, including deploying the decoys staggered in time. 4. The method in accordance with claim 1, including defining effectiveness of the decoy chain by parameters of direction of deployment, distance at which the effect occurs, number of decoys, time at which the effect occurs, or radar reflection cross section. 5. The method in accordance with claim 1, including deploying the decoys of the decoy chain in the direction of the missile or in an opposite direction before or during a search phase of the missile. 6. The method in accordance with claim 1, including programming range staggering of the decoys in the munition. 7. The method in accordance with claim 6, wherein a minimum range staggering between the decoys is 20 m. 8. The method in accordance with claim 1, wherein a radar reflection cross section of the individual decoys is greater than a lock-on threshold of the missile. 9. A device for protecting an object from radar-guided missiles, comprising decoys, which are deployed by a munition, wherein several decoys form a decoy chain, each decoy including a propellant charge and a timing element effective to actuate the decoy at a preset distance from the object and thus from the missile, the preset distance being different for each decoy in the decoy chain.
