| Abstract: | This paper discusses the principle and status of the ADS-B technology,and then gives a brief introduction to the format of the ADS-B signal,based on which this paper analyzes the detection algorithm of the 4 head pulses in detail.Considering the high miss detection ratio of the 4 head pulse algorithm,this paper presents an improved joint fiducial probability distribution algorithm.The simulation results show that the improved algorithm achieves better performance in reducing the miss detection ratio than the formal algorithm. |
