The performance characteristics of a wideband (single-channel) and multicha
nnel energy signal detectors with pseudorandom tuning of the operating freq
uency (PTOF) are considered. An emphasis is placed on a multichannel adapti
ve energy detector (MAED). The effect of interfering signals on the perform
ance characteristics of the MAED are estimated. The characteristic features
of the interception of signals with PTOF are described as applied to repea
ter jamming against radio-communication systems (RCSs) with PTOF.
