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.
