A method and associated decoy for offering a phantom target for protecting land, air or water vehicles or the like as a defense against missiles possessing a target seeking head operating in the infrared (IR) or radar (RF) range, or a target seeking head simultaneously or serially operating in both wavelength ranges. An effective mass emitting radiation in the IR range (IR effective mass) based on flares and a mass backscattering RF radiation (RF effective mass) based on dipoles are simultaneously made to take effect in an appropriate position as a phantom target. A ratio of dipole mass to flare mass of approx. 3.4:1 to approx. 6:1 is employed; and flares presenting a descent rate approx. 0.5 to 1.5 m/s higher than that of the dipoles are used.

Method for offering a phantom target, and decoy

The method offers a phantom target for protecting land, air or water craft or the like against missiles that have a target seeking head operating in the infrared (IR) or radar (RF) range or simultaneously or serially in both wavelength ranges. A mass emitting radiation in the IR range (IR active mass) and a mass back-scattering RF radiation (RF active mass) are simultaneously brought into action in the correct position as phantom target.

Flare mass for a dummy target for producing a selected spectrum

A process to camouflage a device which emits infrared radiation from another device includes forming a wall of particles having a known distribution density between the two devices. The particles emit or absorb infrared radiation from a known surface area. The distribution density, surface area and distances between each device and the wall are such that the wall masks the device to be camouflaged yet does not mask the other device.

In a method for offering a dummy target which simulates the target signature of a subject, such as land craft, aircraft or water craft, to an imaging, radiation-sensitive homing head such as an infrared homing head, a number of active masses are deployed at respective spatial positions, with each mass simulating a portion of the target signature of the subject by emitting spectrally differentiated radiation in the sensitivity range of the homing head. The active masses are deployed at positions to produce a three-dimensional dummy target in which sources of radiation to which the homing head is sensitive are positioned in a manner which mimics the subject.

A method of protecting a ship from missiles with two-color infra-red target seeking heads and which is characterized in that an interference transmitter disposed on the ship sends out exclusively short wave infra-red rays, at least intermittently, the strength of radiation from the interference transmitter being so adjusted that the ratio of short wave to medium wave infra-red radiation is so shifted that the ship cannot be reliably recognized as a target by the two-color infra-red target seeking head.

A process is provided for defending objects emitting an infrared radiation, in particular ships, against missiles, which are equipped with intelligent infrared seeker heads. Following location of the missile, adjacent the object a large area pyrotechnical perturbing radiation cloud, which releases high infrared radiation in a short period of time, which hashes the locking on and pursuit electronics of the seeker head, and subsequently releases a weak infrared radiation for a comparatively long period, is produced between the object and the missile. Immediately following the end of the high radiation phase of the perturbing radiation cloud, several fake target clouds are set up that then lead the missile step-by-step away from the object to be defended. The perturbing radiation clouds are produced by the droppable bodies, whose active masses comprise phosphorus flares and phosphorus pellets.
