The RCS of antennas on a missile-like body

Describes one of the major activities using Roke Manor's anechoic chamber RCS measurement facility. This is a component of Roke Manor's activity in the measurement and prediction of radar signature and stealth characteristics. In particular, a study of the RCS of antennas is described-prompted initially by general interest, and by specific concerns, regarding the effects of mounting antennas on a missile-like body. The material presented describes the anechoic chamber, the measurement equipment and the results of a measurement study intended to investigate the phenomena. The results are divided into two sections. These describe some basic mechanisms, and specific results for the antennas and target body involved. Some precise details, such as target shape, measurement frequencies and absolute RCS levels are referred to only in general terms.<
