摘要
An RF band receiver for concurrently monitoring a plurality of contiguous channels within the RF spectrum to unambiguously detect time-coincident signals. The receiver includes a plurality of transmission paths feeding a like number of digital, mixed-base code channels. Each mixed-base code channel includes a harmonic mixer, an IF amp, a plurality of bandpass-filters and a like plurality of detectors. The outputs of the detectors for each mixed-base code channel are fed to a frequency sorter whose output is a digital frequency word which indicates the frequency(s) of the received signal(s).
