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)
