Barrage jamming is used when there is a need
to jam over a wide bandwidth simultaneously. Barrage jamming
is an attractive technique because a range of different radars
(including frequency agile radars) can be jammed continuously and simultaneously.
The problem with barrage jamming, however, is one of
power. The barrage jammer must spread its power over a
very wide band, which reduces the jammer power in any
one particular band. This is quite different from the spot
or sweep jammers whose entire transmitted power is concentrated in
a relatively narrow bandwidth. Not only is the barrage jammer's
power spread over a wide bandwidth, it may be wasted
if there are no radars operating in part of its
band. Power is the critical success (or failure) factor associated
with barrage jammers.
