1-17. Since each predetermined frequency is jammed individually in rapid order with the
sequential multispot method, each frequency receives full power output of the jammer for a short
period of time. Also, if the cycling is rapid enough, jamming can appear to be continuous at
each frequency. Therefore, sequential multispot jamming uses a single jammer to jam each
frequency _________________ on a _________________ -sharing basis.
(1-17. Answer: individually, time)
1-18. The simultaneous multispot method of jamming uses a single jammer against many
frequencies on a power-sharing basis. If a number of preselected frequencies are jammed at one
time, with the jamming POWER divided equally among the frequencies, the
_________________ _________________ method is used.
(1-18. Answer: simultaneous multispot)
1-19. Since the simultaneous multispot method means jamming several predetermined
frequencies simultaneously, output power is being divided among the frequencies. This means
that no frequency receives full output power from the jammer continuously. Therefore, the
simultaneous multispot jamming technique is indicated if a single jammer is used to
simultaneously jam preselected frequencies on a _________________ -sharing basis.
(1-19. Answer: power)
1-20. The last variation of the spot jammer to be considered is the swept spot, or sweep jammer.
The swept-spot method is the programmed frequency variation, or sweep, of a single spot
jammer within a predetermined frequency band. By using a swept spot, all available power is
concentrated for a short period of time on each frequency in a frequency band, but jamming
signals are not continuous on any frequency.
To jam a band of frequencies by jamming each frequency of the band for a short period
of time, a _________________ -_________________ would be needed.
(1-20. Answer: swept-spot)
