In this type of system, each of the jamming antennas is acting as the signal source for a repeater- type jammer. In skirt jamming, the jammer exploits the phase response of filters in the radar receiver by injecting a strong jamming signal into a region just above or below the filter frequency.
However, one factor that often is overlooked when talking about jamming is radar cross section ( RCS ) of the target. When the range gate is sufficiently removed from the actual target, the deception jammer is turned off, forcing the tracking radar into a target reacquisition mode.
The most common type of deception jammer is the range deception (range-gate stealer), whose function is to pull the radar tracking gate from the target position through the introduction of a false target into the radar’s range-tracking circuits. The relation between radar, jammer power, and jamming effectiveness is well known and …
