Description: Principles of construction of two variants of the passive radio engineering system are offered for aiming of airplane on impulsive ground radar system and radar system continuous radiation. The system contains the surface point of aiming and side free-standing repeater of signals radar system, placed on the airplane. Work of the system is based on taking the bearing radar system on an azimuth from the surface point of aiming and measuring on this point of time of delay of direct and retransmitted from a side impulses or Doppler frequency of the retransmitted signal. Suggestion can provide determination of plane coordinates radar system with exactness, acceptable to aiming on radar system of airplane.
