Conventional monopulse planar arrays designed for Low sum sidelobe levels suffer from high sidelobes in the two different patterns. The monopulse function is obtained by combining the outputs of the four quadrants in a monopulse comparator, hence the amplitude tapering is the same for the sum and the two different modes. The phase reversal and the amplitude discontinuity when forming the difference modes causes the high difference sidelobe levels.
