针对二重模糊积分工程实用化,建立了备域上二重可测函数、单调类上二重可测函数的概念。由此出发,从积分函数选择、积分运算方式等方面修正了现有二重模糊积分理论,并给出基于二重模糊积分的综合评判模型。随后,将该理论用于解决一个较为复杂的评估问题--目标识别效果评估,确定了评估指标、评估因素集、因素集元素的权重选取方式、单个评价向量组的生成方法,构筑了评估模型,进行了仿真实验验证。综合评判过程及结果表明了修正后二重模糊积分的科学性、易用性。

The concept of mobile atmospheric laser communication (MALC) is introduced in this paper. Atmospheric attenuation, turbulence-induced scintillation and beam wander cause deep fades in the beam power and degrade the optical channel. The optical transceiver presented in this paper is designed for a MALC test system. Currently achievable hardware performance capabilities for the MALC terminals are used as input parameters to the analysis. A novel optical transceiver structure is designed. Link margin is analyzed using the MALC analysis software, our optical link analysis program. Data rate, bit-error rate, prime transmit power requirements, optical link margin, pulse width, background signal, aperture quality and atmospheric effects drive the optical transmitter requirements. Results are displayed as required aperture size, aperturenumber and the spacing between apertures for a given range and terminal moving speed. The aperture size is parameterized by data rate, transmitting optical power and wavelength. Si-APD and CCD are selected as the main receive detectors. The receiver aperture, detector size (diameter), receiver speed and sensitivity are the main factors to consider in the design of the receiver.
