Abstract
Telemetry and ranging sidebands may interfere with each other. Theoretical models are proposed for assessing this danger. An interfering sideband may be specular or difiuse. If specular, it looks like a continuous-wave interferer, and a signal-to-noise ratio degradation is calculated as a function of the proximity of the interferer to the range tone frequency (for ranging), or subcarrier (for telemetry with a subcarrier), or carrier (for telemetry without a subcarrier). If difiuse, the interferer increases the efiective noise floor. The theoretical model for telemetry degradation due to a specular interferer is verified by experiment.
