Similar Names

The characteristics of
combined and comb jamming of RCIED activation messages are presented
in this paper. Combined jamming signal is formed as the sum of swept
sinusoidal signal and noise signal, while comb jamming signal means
that its
spectrum has a number of simultaneous discrete equally distant
sinusoidal components, eventually further swept. The performances of
combined jamming are compared to pure sweep and pure barrage
jamming. They are determined on the base of originally developed
simulation program implementation.
Comb jamming is analyzed based on its generation from rectangular
pulse train. It is presented how the selection of ratio of pulse
duration to its period and the number of frequency components in
comb signal influence the obtained jamming signal characteristics.
It is proved that comb jamming is especially advantageous in
relation to sweep jamming when RCIED activation message duration is
significantly lower than the sweep cycle period.
Key words: RCIED;
combined jamming; comb jamming; simulation program; Bit Error Rate (BER);
