This variant of the Antenna Positioner is provided with an auxiliary RF input coupled to an RF signal detector.
These additional components are required when the ATMS is used with the optional RCS Demonstration Accessories, Model 9594-B, to measure and observe the near-field or far-field relative Radar Cross Section (RCS) of reflecting objects (targets). RCS patterns of targets with different shapes are acquired, displayed, and stored using the LVDAM-ANT software the same way as antenna radiation patterns are. The ATMS and RCS Demonstration Accessories allow quasi-monostatic and bi-static RCS measurements to be performed. The standard Antenna Positioner, Model 9506, is no longer required when the Antenna Positioner, Model 9506-A, is ordered.
