SECTION 5: DETECTING SOPHISTICATED TRANSMITTERS
87 REI OSC-5000E
Spread Spectrum Example
Spread Spectrum technology spreads the transmitted energy over a wide frequency
spectrum, making the transmitter more elusive. Due to the method of digital encoding in
the spread spectrum signal, there may appear to be multiple low-level signals that are
frequency hopping. If you are unsure if the signal is a threat, try the procedures described
on page 98 (Suspicious Signals).
The best method to identify potential spread spectrum threats is to rely on the Peak minus
Friendly spectrum display. Using this approach, signals that are unique to the threat
environment are quickly identified.
