Second order discriminant function for amplitude comparison monopulse

A novel three-receiving-elements amplitude comparison monopulse direction finding (DF) technique is introduced. An appropriate second-order discriminant function is chosen for this technique. Then simulation is used to compare its accuracy with that of the two-receiving-elements DF technique. Different sources of error were taken into consideration, such as receiver noise, pattern errors, amplitude imbalance, and mechanical and quantization errors. It is concluded that the three-receiving-elements amplitude comparison monopulse system is always more accurate than the two-elements system, especially around the receiving array axis.<
