摘要： An improved monopulse radar system wherein target return signals received by a plurality of antenna elements are corrected with correction signals derived within the system in response to pilot pulses. The improvement comprises a plurality of receiver channels, each receiver channel being coupled to a single one of the plurality of antenna elements. The improvement also comprises means for generating a first set of quadrature components of video signals developed in the plurality of receiver channels in response to the pilot pulses received by the plurality of antenna elements, and for generating a second set of quadrature components of video signals developed in the plurality of receiver channels in response to return signals from the target received by the plurality of antenna elements. Digital signals representative of the first and second sets of quadrature components of video signals are generated. The digital signals representative of the second set of quadrature components of video signals are digitally corrected with the digital signals representative of the first set of quadrature components of video signals to produce digital signals representative of corrected target return signals. Signals corresponding to the angle of the target relative to the plurality of antenna elements are generated in response to the digital signals representative of corrected target return signals.
