METHOD FOR PROTECTING RADAR STATION AGAINST ANTI-RADAR ROCKET SHELLS BASED ON PASSIVE RADIATION SOURCES Russian patent published in 2006 - IPC G01S7/38 

FIELD: radio engineering.

SUBSTANCE: method involves distracting anti-radar rocket shells to additional radiation source having transceiver and passive radiation source separated to some distance from each other. The additional radiation source transceiver is placed on balloon above the passive radiation source at altitude giving no damage to be inflicted thereon when hitting the passive radiation source with an anti-radar rocket shell. The additional radiation source signal-emitting time is determined from formula t_em= t_n+T_n -ac+dc+bc, where t_n is the reception time, T_n is the radar station probing signal repetition period, a is the distance between radar station and passive radiation source, d is the distance between additional radiation source and passive radiation source, c is the light propagation velocity. Additional radiation source pulse duration is equal to radar station pulse duration enlarged by time the electromagnetic wave passes the distance equal to 2b.

EFFECT: high protection level of additional radiation sources.
