ABSTRACT:
A pulse detecting equipment includes a log compression processor (105) for logarithm-converting signal levels of a reception signal received at an antenna and input therefrom, with maintained frequency components of the reception signal as input, an AD converter (106) for converting the reception signal as logarithm-converted in signal level, from an analog form into a digital form, a first detector (110) for limiting the reception signal as converted into the digital form to a band of a prescribed first frequency, to obtain a signal, to detect signal levels thereof, a second detector (111) for limiting the reception signal as converted into the digital form to a band of a prescribed second frequency smaller than the first frequency, to obtain a signal, to detect signal levels thereof, and a pulse detector (113) for use of a result of comparison between signal levels detected at the first detector and signal levels detected at the second detector, to detect pulses of a prescribed frequency as a signal transmitted to own equipment.
