摘　　要：为研究组网传感器协同探测对目标发现概率的提升作用,对信息共享条件下的传感器发现概率进行了建模。首先给出了单传感器独立探测条件下的发现概率计算公式;其次分析给出了信息共享条件下单传感器发现概率的求解方法;之后采用K/N判决准则计算传感器组网探测概率;最后通过仿真分析了不同参数对信息共享条件下传感器发现概率的影响,得出了一些有意义的结论。To study the promotion effect of networked sensor cooperative detection on detection probability,a model of detection probability was built up based on information sharing.Firstly,the formula for calculating the detection probability of single sensor in independent detection was presented.Then,the algorithm for calculating the single sensor detection probability based on information sharing was given,and the sensor network detection probability was calculated out by using K/N judgment model.Finally,the influence of several parameters on the detection probability under information sharing was analyzed through simulation,and some significative conclusions were gained.
