Sweep
jamming within a frequency range is a compromise between wideband and narrow-band
jamming.
Since we only need to jam a digital signal one third of the time, a 33%-duty-factor pulse will be adequate for effective
jamming.
Deception
jamming is mainly a countermeasure used against search and tracking radars.
The formula for burn-through range for each kind of
jamming is just the appropriate J/S equation (presented with all terms defined last month), [TABULAR DATA FOR TABLE 1 OMITTED] but rearranged to isolate the range term.
Understandably, the operational parameters of RF
jamming systems are subject to classification restrictions.
EDO has been the leader in interference-mitigation and
jamming technology for decades," said James M.
The program's intent is to realize accurate navigation and guidance capability in the presence of GPS
jamming at a much lower cost by integrating a set of components whose costs have been driven down by the competition resulting from high volume commercial applications.
