摘要:

针对国外星载AIS（Automatic Identification System）系统由于时隙冲突导致检测概率降低的问题，提出了一个检测概率计算模型。通过分析影响检测概率的各种因素，得出概率计算的算法，并对算法进行了理论分析。对于某个具体的星载AIS系统，将系统参数代入到该模型中，可以得到该系统的检测性能，从而为实际工程提供理论参考。

Abstract:

For the problem that the detection probability of foreign spacebased AISs(Auto m atic Identification Systems) is reduced due to time slot collision, a calculat ion mode l of detection probability is presented. A calculation algorithm is given by ana lysing all factors influencing the probability and the algorithm is an alysed in theory. For a specific spacebased AIS, detection performance can be obtained according to the model using the system parameters, which provides theo retical reference for practical projects.
