摘要
A wideband microwave digital receiver comprises an antenna, an amplifier, and a digital IFM device for measuring the frequency of the received signal or signals. A consistency indicator indicates the consistency of the frequency measurements and is calculated by analyzing the values taken by said measurements obtained over two consecutive transforms. The presence of signal pulses at the input of the receiver is detected when said indicator signals the consistency of at least one frequency measurement.
