| 摘 要： | 采用信号检测的统计思想,在详细分析雷达接收机各种噪声大小与概率分布、计算空间背景光大小和光谱特性的前提下,基于信号检测理论中的虚警概率和发现概率提出了一种能直接计算非相干检测方式下所需最小光功率的方法。仿真结果表明,由该方法计算的最小光功率能够更好地优化激光雷达系统的性能。

| Abstract: | In this paper, the noise of receiver and its probability distribution are analysed, and the spectrum of outer space is calculated. Then, a new way to calculate minimal detectable power of laser radar is given, which is deduced on the base of signal detection and two statistic concepts: false alarm rates and detection probabilities. System simulation proves the minimal detectable power calculated by this method can optimize the laser radar system. |
