Abstract:
A radio frequency (RF) signal warning system for detecting and providing an indication of RF signals in at least one RF band, wherein said RF signals include at least one pulsed RF signal having a pulse repetition frequency (PRF), said system comprising:amplifying and conditioning means for amplifying and conditioning said RF signals to produce corresponding amplified and conditioned RF signals;RF detection means for envelope detecting said corresponding amplified and conditioned RF signals to produce corresponding envelope detected RF signals;video amplifying means for video amplifying said corresponding envelope detected RF signals to produce corresponding video bandwidth signals, wherein said corresponding video bandwidth signals corresponding to said at least one pulsed RF signal have the same PRF as said at least one pulsed RF signal;processing means for processing said video bandwidth signals to determine an RF band of said at least one RF signal and a PRF range of said at least one pulsed RF signal, wherein said processing means generates and transmits audio and visual control signals for indicating said RF band and said PRF range; andat least one remote unit, responsive to said audio and visual control signals, for providing audible alarms and for providing visual indication of said RF band and said PRF range.
