Zusammenfassung:	PURPOSE:To measure the sum pattern and the difference pattern simultaneously by connecting a sum channel terminal and a difference channel terminal of a monopulse antenna to an input terminal of a receiver with a switching. CONSTITUTION:A microwave signal sent from a transmitter 1 is radiated to a monopulse antenna 3 to be measured from a measuring antenna 2. The sum channel terminal 3a of the antenna 3 is connected to a terminal 8a of a microwave switch 8 while the difference channel terminal 3b to a terminal 8b thereof. In a receiver 6, the sum channel and the difference channel signal are measured synchronizing a change-over signal (a) for changing over the switch 8.
