| Abstract: | Ground base jammer cannot provide air space dominance for Ethiopia due to the massive
highland complex of the country characterized by high rising mountains and dissected
plateaus. In addition to this if high-flying systems and unsecured air space are piloted; it may
be too dangerous in some situation to over fly certain areas. To overcome the above problem
this thesis provides a good solution which is implementing a jammer on a UAV-platform. In
this thesis, the Electronic Attack systems and the performance degradation of Surveillance
Radar (P-15) due to UAV-platform jammer are described and analyzed. The jammer
parameters were collected from simulation result as well as standards data. Using these
parameters the effect of jamming on detection of targets is evaluated. The evaluation is
performed by finding the change in radar SNR due to jamming and range reduction. The
Predator-UAV type is the base system for this study much like the stand-off jammer.
However, since the distance is closer to the radar, the EIRP jamming requirements are
reduced. Stand-in jammer requires 6.3 watt at 50Km and stand- off jammer need 50 watt at
130Km from victim radar i.e. sufficient to jam P-15 Radar. For economical aspect stand-in
jammer is much preferable for our country, since it provides 93% range reduction with a
minimum amount of power. |
