A jamming technique aiming at phase-coded stepped-frequency radar is proposed.The modulation characteristic of phase-coded stepped-frequency signal and multi-carrier phase-coded signal is analyzed.On the basis of the above
a new jamming technique of multi-carrier phase-coded repeater is presented.The new jamming effectiveness is analyzed theoretically.This method can make phase-coded stepped-frequency radar form several precede and lag lifelike false targets.The relativity of
m
series in equal length is studied.The opt principle of jamming signal sub-carrier and phase-coded series are presented.The conclusion is proved by simulation experiment.The studied result indicates that this jamming technique is superior to jamming technique of intermittent-sampling predict
