Abstract

PURPOSE:To measure the phase quantity of a reception system in an actually packaged state by inputting an attenuated transmission signal to an antenna array element, and determining the phase quantity of the reception system by the phase quantity of the leakage signal of the element into the reception system and the phase quantity of the output transmission signal of the element. CONSTITUTION:The transmission signal attenuated with an attenuator 20 is applied to an active phased array antenna element 1 without leaking from a circulator 11 and leaks from a circulator 4. It is applied to a phase measuring device 21 to which the transmission signal is applied through a saturation receiving amplifier 5 activated by a switch 7, a circulator 11, etc. Then, the sum of the phase quantity by the transmission and reception systems is detected by the device 21. On the other hand, if the transmission signal of the element 1 is applied via a horn antenna 14 to a phase measuring device 22, the phase quantity of the transmission system is detected, and by the difference in the detected values of both devices 21, 22, the phase quantity of the reception system of the active phased array radar is measured in an actually packaged state.
