Influence of Antennas on Generated Radar Targets when Using Radar Target Simulators

This paper presents the effects of antennas on generated targets when using radar target simulators. A short introduction about radar target generators is given and the reason for ghost targets is discussed. Afterwards, effects of distortion on the generated targets are estimated by means of amplitude and phase change. Different horn antennas were simulated, to examine reflection effects on aperture and mismatch. Furthermore, methods to diminish the impact on the generated targets are simulated and presented. This includes aperture change, attenuation, matching, and polarization changes in the test setup.
