Aeronautical Mobile Telemetry and Radar Transponders – An Interference Study in C-Band-Part 1

Test missions are gradually migrating telemetry operations to lower and middle C-band as these bands offer access to 600MHz of available Aeronautical Mobile Telemetry (AMT) bandwidth. C-band is also the band of operation for most radar transponders used on the Test Ranges today, raising concerns about potential interference between these systems. This study aims to systematically assess and quantify performance degradation between telemetry and transponder systems when co-located on test platforms. Furthermore, it seeks to develop strategies for mitigating potential interference conditions between telemetry and transponder systems.
