Aircraft position verification with one satellite based on Doppler shift change
Satellite-based automatic dependent surveillance-broadcast(ADS-B)is an important technology for wide-area aircraft surveillance.To solve the problem of false target interference existing in the satellite-based ADS-B system,a position verification method with one satellite based on Doppler shift change was proposed.First,the system model of satellite-based ADS-B was presented.Then,the formula for the Doppler shift change of aerospace link was theoretically provided.Furthermore,the Kolmogorov-Smirnoff(k-s)test was used to verify the authenticity of the ADS-B position message.Finally,the correctness and effectiveness of the proposed scheme were verified by computer simulation.The simulation results show that the probability of detection of the proposed method is more than 97.75%,and the false dismissal probability is less than 4.50%.In addition,only one low-orbit satellite is required for monitoring,and it is not sensitive to positioning errors of aircraft and satellites.
