Abstract:
1. A pulse detecting equipment comprising: a logarithmic compression processor configured to logarithm-convert 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 (Analog/Digital) converter configured to convert the reception signal as logarithm-converted in signal level, from an analog form into a digital form; a first filter configured to limit the reception signal as converted into the digital form to a band of a prescribed first frequency to obtain a first signal; a second filter configured to limit 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 second signal; a first detector configured to detect signal levels of the first signal; a second detector configured to to detect signal levels of the second signal; and a pulse detector configured for use of a result of comparison between first signal levels detected at the first detector and second signal levels detected at the second detector, to detect pulses of a prescribed frequency as a signal transmitted to own equipment.
