Analysis on detection probability of satellite-based AIS affected by parameter estimation

In order to analysis marine detection performance of the satellite-based AIS receiving system and provide a reference for related algorithms, the relationship between signal detection bit error rate(BER) and detection probability is analyzed and simulated, besides, the detection BER is simulated at different parameter estimation accuracy. Simulation results show that the energy ratio of any two signals of the mixed signals must be greater than 6dB for the receiving system, while the error of the amplitude estimation, frequency offset estimation and delay estimation must not be higher than a value. The simulation model of detection probability introduced can be referenced in the design of the satellite-based receiving system.
