<p>PROBLEM TO BE SOLVED: To provide a monitoring system which can simultaneously execute a monitoring processing operation in all frequency bands even when the system is operated in a plurality of frequency bands. SOLUTION: In a transmission-signal processing means 40, a transmission reference signal 30A is converted into a plurality of different radar frequency bands so as to be composited. A transmission signal 32 is generated so as to be output to a transmission-reception monitoring changeover device 7. In a reception-signal processing means 41, the signal component is frequency- converted for every radar frequency band contained in a reception signal 35 from the changeover device 7. Respective extraction signals 36A, 36B are generated so as to be outputted to an amplitude and phase measuring circuit 15. In the circuit 15, an amplitude and a phase in a monitoring route are measured and processed in parallel on the basis of the extraction signals 36A, 36B obtained by the processing means 41 and on the basis of the signal 30A.</p> |
