Background. Telemetry information is very important for confirming the flight performance and assessing the technical condition of the aircraft. In difficult jamming conditions, information-significant fragments of telemetry control results can be lost or distorted. In this regard, the development of methods and algorithms for recovering telemetric information is of great practical importance.
Materials and methods. To restore telemetry information, it is proposed to use the method of singular-spectral analysis of pre-detector recording of a group telemetry signal. At the same time, a hypothesis was put forward about the influence of the parameters of the singular-spectral decomposition on the reliability of the restoration of telemetric information.
Results. By means of simulation modeling of restoration processes, a range of optimal parameters for the use of singular-spectral decomposition of pre-detector recording of a group telemetry signal has been formed, providing a high degree of reliability of information restoration.
Conclusion. In difficult conditions of interference, characterized by a low signal-to-noise ratio, the use of the optimal parameters of the telemetry information recovery algorithm based on the application of the method of singular-spectral analysis of the predetector signal recording allows a high degree of reliability in the presentation of telemetry parameters.
