Definitions
- the invention relates to a protective device and a protective measure for a radar system on an object, in particular against an anti-radiation missile (ARM) - attack.
- ARM anti-radiation missile
- New ARMs are now prepared for this defensive method and seek their target by other means. Furthermore, they are equipped with an IR seeker, own active radar or GPS data etc. Thus, the previous strategy of avoiding emissions by switching off the radar transmitter against new ARMs is no longer sufficient.
- the invention takes on the task of demonstrating a new protective device and protective measure, with which this fact can be counteracted.
- the invention is based on the idea to combat an ARM now by active countermeasures.
- Active countermeasures may be the deployment of decoys.
- a method and apparatus for protecting military military equipment from searchers also describes the DE 101 17 007 A11.
- the aforementioned solutions relate to the familiar deception and disguise of objects which require the presence of a radar signature of a target, the radar reflection surface or a radar return cross section or other sources.
- active transmitter decoys
- These are usually very expensive and also only used once.
- these channels must be controlled so that the deception succeeds and an ARM is directed to the decoy.
- the US 4,130,059 A deals with a decoy material that contains a passive source that is physically offset / separated from the active source, but radiates frequencies that have not been transmitted by the active source, thereby creating the illusion of multiple independent sources. These decoys are deployed for protection and explode, then act according to their task as a fake target.
- the use of passive transmitters / decoys is now provided in contrast to the aforementioned solutions. It uses decoys that work according to the reflection principle.
- the own radar preferably radiates these decoys.
- the radiation reflected by the decoys in the direction of the ARM has exactly the same characteristics as the direct radiation of the radar itself. Thus, the ARM can not distinguish whether they are decoys or the right radar.
- the decoys are made of a reflective material, such as aluminum, and are stored in a container / canister. This can be brought to a predetermined height at an ARM attack and disassemble there. This forms a cloud of reflective body, which are now preferably illuminated by its own radar. The reflected radiation towards the ARM is a better target for the ARM because the signal strength is greater than that coming directly from the radar. The cloud deflects the ARM and past the target.
- a serious advantage compared to the previous protective measures is that the radar continues to operate even in the event of an attack, thereby saving important times.
- these decoys can also be used to confuse an IR seeker head. If they also reflect in the IR range, the IR signature of the environment from the decoys will be given to the seeker head of the ARM. This means that the ARM sees the IR signature of the radar twice, that of the actual radar and its mirror image. Now, working with a hot source on the radar, which can only be seen in the mirror image, the ARM is confused in addition to the radar emission by an IR illusion.
- the cloud consisting of these reflective decoys
- the ARM's own radar can be influenced, since the cloud can represent a larger object than the target and thus is more attractive to the ARM radar.
- a carrier 1 for example an aircraft, delivers an ARM 2 to a vehicle 3 with radar 4, the ARM 2 switching to the radar signal of the radar 4.
- Radar 4 may be, for example, the proprietary SKYRANGER Search Radar and Control Center.
- the search radar determines the incoming ARM and activates the countermeasure or protection measure.
- the rotating radar antenna 4. 1 is stopped and aligned opposite to the direction of flight of the ARM 2.
- the decoys 5 are thrown upwards or spent ( Fig. 2 ), which is then illuminated by its own radar 4, represents an emission source for the ARM 2, on which it is located as in Fig. 3 shown turns on to thereby fly in exactly this height at the radar 4 and thus the vehicle 3 over ( Figure 4 ).
- the decoys 5 are preferably in a container (not shown in detail) on the vehicle 3. A direct proximity to the radar 4 is preferred. This container can be brought to a predetermined height. There he is then opened so that he automatically releases the decoys 5 and they can perform their task.
- strip-shaped bodies 5 are made of conductive material and have, for example, approximately half the wavelength of the electromagnetic field emitted.
- the container thus releases the decoys for the protective measure.
- the bodies 5 form, for example, a half-wavelength dipole cloud / wall 6 behind the radar 4 and acts as a large scattering object 7 (FIG. Fig. 3 ).
- the radar 4 now irradiates this wall 6 (radiation 8) and the viewfinder of the ARM 2 receives this scattering (radiation 8).
- This reflected radiation (8 ') is much more interesting for the ARM 2 than the radar 4 itself, which itself does not transmit in the direction of attack ( Fig. 4 ).
- SKYRANGER determining the distance of an object passing through the atmosphere
- a passive sensor is in the DE 195 46 873 C1 described.
- the countermeasure is then activated in the manner described.
- another radar could be provided which illuminates the decoys 5. In this case, however, the actual radar 4 is to be positioned opposite the attacking ARM 2 so that it is not recognized by it as a source.
