Due to its high-precision angle measurement performance, monopulse technique plays a key role in fields such as remote sensing and space surveillance. The accuracy of monopulse angle measurement depends on the received amplitude and phase information. This paper studies the design of a monopulse amplitude system for use in an S-band passive seeker system with an angle error of less than 2.2 degrees and an angle scan of -20 degrees to +20 degrees. The proposed design uses four helical cavity antennas with right-handed circular polarization, each with a gain of approximately 2.9 dB and a total gain of 7 dB. Using the characteristics of the arrayed antenna and the monopulse radar relations, the angle error for the signal-to-noise ratio of 20 dB is 2.2 degrees.The proposed design uses four helical cavity antennas with right-handed circular polarization, each with a gain of approximately 2.9 dB and a total gain of 7 dB.
