多波段光学探测系统的探测概率研究

Research on Detection Probabilities of Multi-Band Optical Detection Systems

  • 摘要: 针对光学联合探测子系统探测概率的不同特点,提出一种新的系统工作模式,使系统的最终探测概率有较大提高。当子系统的探测概率均比较低时,直接对子系统的探测数据进行融合,可以获得较高探测概率;当各子系统探测概率相差较大时,可先对探测数据进行选择,然后再进行数据融合,这样可以在总探测概率减小不大的情况下,使虚警概率明显降低。

     

    Abstract: A new operation model for joint optical multi-band detection systems is provided corresponding to the different characters of the detection probabilities of subsystems. It leads to a higher over-all detection probability. The joint optical detection system is able to operate under different models when detection probabilities of subsystems are low and when there is big difference among the probabilities. The joint optical detection detection system directly conducts data fusing under the former condition. And information from the subsystems is chosen before entering the fusion center under the latter condition. In this way, the false-alarm probability of a joint optical detection system reduces obviously comparing with direct data fusion.
