激光测距中基于阵列探测器的多通道数据处理方法研究

Satellite laser ranging (SLR) technology is one of the most accurate modern geodetic techniques. The significance of satellite laser ranging is that it has a wide range of scientific applications. The lunar laser ranging (LLR) and space debris laser ranging (DLR) technologies developed by SLR technology are of great significance in scientific research..In the application of superconductor detector array and multi-channel event timer in laser ranging technology, the number of photons in each laser pulse is detected and recorded, each of the main wave moment may correspond to multiple echo time data, which is no longer the traditional laser ranging as the main-echo signal does not have a one-to-one relationship, but a one-to-many relationship. Superconductor detector array operates in the free state, a state of receiving echo signals continuously, which results in a significant increase in the amount of data. The response time jitter of the superconductor detector array and the board-to-board measurement error of the multi-channel event timer also influence the ranging data. These raise new requirements for data processing..Based on the application of superconductor detector array, we research on multi-channel data processing method, integrate the data into high quality data and improve the accuracy. It is of great significance for the scientific application of laser ranging data.

卫星激光测距（SLR）技术是精度最高的现代空间大地测量技术之一，进行卫星激光测距的意义在于其高精度数据具有广泛的科学应用。由SLR技术发展而来的月球激光测距（LLR）和空间碎片激光测距（DLR）技术都在科学研究上有重要意义。.超导阵列探测器和多通道事件计时器在激光测距技术中的应用，使每个激光脉冲中被探测并记录的光子数增加，每个主波时刻可能会对应多个回波时刻，数据不再是传统激光测距中的主回波信号一对一关系，而是一对多的关系；超导阵列探测器工作在自由状态，一直处于接收回波信号状态，导致数据量大大增加；超导探测器的响应时间抖动和多通道事件计时器的模块间测量误差也会对测距数据产生影响。这就对数据处理提出了新的要求。.本项目在超导阵列探测器应用基础上，研究多通道数据处理方法，将数据融合成高质量数据，提高激光测距精度，这对于激光测距数据的科学应用具有重要的意义。
