A radar capability display apparatus utilizing radar theory equations which are stored in a computer to relate the measured characteristics of interference signals in radar return echoes to determine the amount of radar performance degradation that the interference signals create. These loss of performance factors which are obtained at each antenna beam angle and range, are displayed on the radar\s screen as the radar capability display.
