摘要
There is provided a time-division duplex transmit-receive apparatus in which the respective amplitude and phase characteristics of N sets of transmitting unit-receiving unit pair connected with N antenna elements are corrected all together and at the same time. At the time of reception, the reference signal from reference signal generator is branched into N reference signals. The branched reference signal is applied to the reception system through the transmit-receive switching switch. The reception-side error detector detects the error between the output signal of the reception-side amplitude-phase correction circuit and the reference signal to control the reception-side amplitude-phase correction circuit so that the error becomes zero. At the time of transmission, a part of transmitting signal is applied to the reception system through the antenna path. The transmission-side error detector detects the error between the output signal of the reception-side amplitude-phase correction circuit and the transmitting signal to control the transmission-side error detector so that the error becomes zero.
