Abstract

Aiming at the problem of high-precision recognition of satellite signals, this paper proposes a Doppler-shift oriented dynamically optimised LSTM satellite signal recognition method, which utilises the effect of Doppler shift on satellite communication signals of different orbits and combines the differences in the modulation methods of communication signals of different regimes to realise the identification of satellite signals, and constructs a satellite signal recognition model using a neural network combination of CNN-LSTM, and the satellite signal recognition accuracy performance reaches 99% in the presence of In the presence of Doppler shift, the simulation is based on the signal samples collected from the air port, and the accuracy performance of satellite communication signal recognition for typical regimes such as BPSK, QPSK, QAM, etc. reaches 99.02%.
