Abstract

PURPOSE: To enable to determine the area of existence of signal source, through the provision of the gate circuit passing only the signal having the characteristics measured with the conversion unit which detects the fastest signal and its number through the output circuit and not passing the outputs of other conversion units.
CONSTITUTION: After the output of a plurality of conversion units 1aW1n is amplified, the AR signal characteristics is analyzed with the signal characteristic analysis circuit 5aW5n and the output is digitized. The arrival of signal is judged with the comparison circuit 4 for the signal amplified. The gate circuit 6 decides the monitor area for each set and only the signal characteristics of the conversion unit measuring the fastest signal within the area is passed through the output circuit 7 and the gate is closed to the output of the conversion units measured with delay. Accordingly, the area in existence of signal source in the monitor area required can be determined and the measuring system not subject to the signal propagated from the surrounding can be made.
