Antenna Performance Verification at Launch Site. A Feasibility Study on Preflight Performance Testing of Stripline Slot Arrays Mounted on a Rocket

摘要

The Physical Science Laboratory/NMSU made a feasibility study for preflight testing of cylindrical stripline arrays at the launch site. Far-field radiation patterns were compared to near-field probe measurements. Various array damages were simulated. The results showed a good correlation between the near-field probe measurements and the far-field patterns. The conclusion drawn from the study was that damaged arrays could be detected by near-field probing in the field. However, intermittent problems such as pinched coaxial cables and loose connectors may go undetected. (Author)
