Signals such as a transmission start signal and transmission timing are sent to the transmitter side through the optical transmission interfaces (8a), (8b) and the optical transmission cable (9), and are sent to the transmitter side (2) and the transmitting antenna (1, ) will be sent. The transmission power during transmission is monitored by the power monitor 00, and after being A/D converted by the A/D converter ALL, it is transferred to the receiver side. The signal processing device simultaneously processes the received power obtained from the receiver section (7) and the transmitted power from the power monitor θω, and records them by the data recording device (14). Therefore, RcS can be measured with high accuracy using the transmission power and reception power planned in real time.
