Radar cross section measurements were made on Teledyne Micronetics Radar Range using C-band one nanosecond pulses. The radar target was made up of retrodirective Luneberg lenses variously deployed on a turntable. The number of lenses varied from two to six. For each deployment of targets, the impulse response was experimentally determined with the help of a sampling scope and the complex conjugate of this impulse response was synthesized using power splitters and delay lines. This signal was then transmitted and the RCS enhancement was measured by reducing the level of the transmitted power until the maximum response was equal to a previously established reference level. Subsequently additional power splitters and delay lines were utilized to synthesize matched receiver response and a similar comparison technique was used to measure the increase in the RCS. The configurations which were tried included equal and unequal spacings and path geometries where the individual reflecting centers were separable and cases where they overlapped. The observed value of RCS enhancement were compared with the theoretical values and it was demonstrated that the agreement between the two values was in general well within one dB. Author
