Abstract : The present invention is digital open-loop sidelobe canceller for decorrelating signals by removing correlated components. The invention has inputs for receving n pairs of digital sample values representing the digitized in-phase components and quadrature-phase components of the output of the main radar receiver and also of at least one auxiliary radar receiver. These data samples are stored in memory for later processing and are also furnished to computation networks which calculate weighting coefficients which are processed as real numbers. These real number weighting coefficients are utilized to subtract calculated real number values from the sample values representing the digitized in-phase and quadrature-phase components of the output of the main radar receiver.
