| Summary: | International Telemetering Conference Proceedings / October 25-28, 1999 / Riviera Hotel and Convention Center, Las Vegas, Nevada === Coupling a distortion-free telemetry signal from an encanistered missile by using a
pickup antenna inside the canister can be difficult, because the RF energy leaving the
missile antenna travels through the canister and is reflected and absorbed in a complex
manner before being received by the pickup antenna. In this paper the distortion incurred
by a PCM/FM signal is described and used to predict the resulting distortion on the video
after demodulation. Effects on bit error rate are presented as a function of delay distortion
and bit rate. A demonstrated method of receiving a relatively undistorted telemetry signal
using a pickup antenna is described. |
