Abstract: |
Starting from the generation mechanism of chaotic pseudo code sequence
, this paper analyzes the characteristic and method that can be used by on-coop
erator from the detecting of quantified chaotic telemetry signal, identification
of real number chaotic telemetry signal and parameter estimation of chaotic telemet
ry system, respectively. The methods about chaotic telemetry signal detection ba
sed on Duffing oscillator, chaotic telemetry signal identification based on phas
e-space reconstruction and chaotic telemetry parameter estimation based on chao
s synchronization are proposed respectively. Simulation analysis shows that the
proposed methods can be used by non-cooperator to analyze the chaotic telemetry
signal. |
Key words: chaotic telemetry signal detection parameter estimation non-cooperative analysis |
