摘　　要：如何合理而有效地设计成像激光雷达系统 ,是进行成像激光雷达系统研究的关键 ,设计时必须充分考虑各种参数之间的相互关系 ,根据所提出的指标 ,选择激光器和探测器及其它元器件。以二极管泵浦固体Nd∶YAG激光器为光源 ,以探测的统计学为基础 ,从作用距离、探测概率、虚警概率、信噪比等方面研究了成像激光雷达系统的性能 ,探讨了成像中实际影响成像像素数的因素 ,为成像激光雷达系统的研究提供必要的理论依据。It is crucial to design a rational and effective imaging laser radar system for the research of the imaging laser radar The relationship between many parameters must be considered adequately The laser source and the detector and some other components are chose on the basis of the required index A diode pumped solid state Nd∶YAG laser is selected as the laser source The performance of the imaging laser radar system is researched in the light of detection statistics related with range, probability of detection, false alarm rate and signal to noise Factors affecting the actual detected pixels for the radar is discussed The basis for the imaging laser radar design is offered
