研究目的
To introduce the progress of laser ranging technology at Shanghai Astronomical Observatory, including upgrades to the Satellite Laser Ranging (SLR) system with high repetition rate, improvements in system performance, and advancements in space debris laser ranging technology.
研究成果
The SLR system at SHAO has been upgraded, leading to improvements in the quantity and quality of observational data and system detection capability. The development of SLR technology with 10 kHz repetition rate and space debris laser ranging system has enhanced the detection of weak laser echo signals. Infrared laser ranging technology and laser ranging based on multi-telescopes receiving were also researched, showing potential for improving laser detection capability for space targets.
研究不足
The paper does not explicitly mention limitations, but the challenges of high-repetition-rate SLR such as severe influence of back-scatter, low signal-noise ratio, and high working frequency of subsystem are discussed.
