FIELD: radio engineering, communication.
SUBSTANCE: method involves launching a carrier rocket with a reference reflector, irradiating the reflector with radar signals, receiving and measuring the amplitude of reflected signals, transporting an angle reflector to an altitude greater than 100 km as an effective radar cross-section reference, said angle reflector being in form of two flat radar-reflecting faces, turned by a fixed angle α in the range from (90-Δ)° to (90+Δ)°, where Δ is defined by the relationship: 0<Δ<18λ/a, λ is the wavelength of the radar station being calibrated, a is the dimension of the face of the angle reflector, wherein before launch, the angle reflector is mounted on the outer side of the lateral surface of a controlled stabilised platform with a system for orientation in three plates; the controlled stabilised platform with the angle reflector are mounted on the last stage of the carrier rocket. The carrier rocket takes the controlled stabilised platform, on a ballistic trajectory, to a given point in the observation zone of the radar station being calibrated, where the controlled stabilised platform is separated from the carrier rocket. The position of the centre of mass of the controlled stabilised platform relative to the position of the radar station being calibrated is determined using GLONASS and/or GPS navigation system receivers and an on-board digital computer system. The on-board digital computer system of the controlled stabilised platform calculates and determines the spatial position of the bisector of the angle of the angle reflector relative to the line of sight of the radar station being calibrated. Based on the calculation data of the on-board digital computer system, the platform orientation system aligns the bisector of the angle of the angle reflector with the line of sight of the radar station being calibrated. Further, the angle reflector is spun around an axis which coincides with the bisector of the angle between its faces. The angle reflector is then separated from the controlled stabilised platform, wherein the main lobe of the scattering pattern of the angle reflector is directed towards the radar station and its maximum coincides with the line of sight of the radar station.
EFFECT: high accuracy of calibrating radar stations.
