The presently disclosed subject matter includes an active protection system and a method, dedicated for detecting, locating, and incapacitating beam-riding missiles and in that way protecting an asset from being targeted by the missile. According to some examples following receipt of a threat-indication, the active protection system estimates a location of a beam used for directing a threat (e.g., ATGM) to the target and launches an aerial platform that flies in the opposite direction along the beam until it meets and incapacitates the incoming threat.

FIELD: radar technology.SUBSTANCE: invention relates to passive methods of protecting radar stations (RLS) from homing high-precision weapons (HPW) with a passive homing head (PHH), which include anti-radar missiles (ARM). The radar station and an additional radiation source (ARS) synchronized with it emit coherent signals in the direction of the spatial position of the ARM. These devices represent a source of spatially diverse interference to the passive homing head of a missile. The normal to the phase front of the resulting electromagnetic wave differs from the normal to the phase front of the radar. As a result, the missile's passive homing head is oriented in the direction of the false target, which is different from the direction of the protected radar. The condition for the interference impact is the provision at the input of the receiving antenna of the PGSN of an inversion zone of the total wave front of the resulting signal of the radiation sources with certain amplitude-phase relationships, as well as the provision of a change in the angular velocity of rotation of the missile-target line of sight.EFFECT: increased radar's protection against anti-missile missile attacks by diverting its guidance trajectory to a false point from the protected radar.1 cl, 2 dwg
