摘要

    摘要
  • 摘要: 为使星载激光测高仪满足测量精度的需求，分析了接收放大器部分的设计原则与要求，对带宽、信噪比、探测灵敏度和放大倍数等主要性能参数进行了理论分析与研究，得到了性能参数的关系和优化的参量。理论结果表明，在激光测高仪测量范围为450 km~650 km，激光脉冲宽度为8 ns~12 ns，工作波长为532 nm与1 064 nm的情况下，对放大器性能参数进行分析计算，可以满足虚警率为1%的星载激光测高仪的设计需求。
    Abstract: In order to meet the demand of satellite laser altimeter (SLA) for high measurement accuracy, the design principles and requirements of receiving amplifier were analyzed. The parameters relationship and optimized parameters were given after some main performance parameters such as bandwidth, signalnoise ratio(SNR), detection sensibility and amplifier gain were analyzed and researched in terms of theory. The results show that SLA could achieve the measurement accuracy of false alarm rate of about 1% with the measuring range of 450 km~650km, pulse width of 8 ns~12 ns, working wavelength of 532 nm and 1064nm.
