Research on Fm Telemetry Signal Demodulation Based on Instantaneous Frequency Measurement

Abstract:

According instantaneous frequency measurement theory, we propose a new PCM/FM telemetry signal demodulation method. This paper introduces the basic principles of this demodulation method and implementation process, the influence of instantaneous frequency measurement accuracy and the impact of factors on the Doppler frequency demodulation performance is proposed to improve the accuracy and instantaneous frequency measurement method demodulation performance. Simulation results show that this method is superior demodulation performance, strong anti-jamming capability, ease of software programming and DSP devices to achieve.
