Research on Mid-Range Measurement of Space Non-cooperative Target Based on ToF

Abstract

This paper mainly analyzes the application of laser Time-of-flight (ToF) measurement in the measurement of medium-range distance of non-cooperative targets in space, in order to handle the problem of different measurement methods in the distance measurement of non-cooperative targets in space. Firstly, the different methods of distance measurement of non-cooperative targets in space are summarized. Then, the principle of laser measurement and the description of different laser measurement systems are introduced. The performance of pulse-ToF measurement system to measure the mid-range distance measurement is also analyzed. As the result, the relative distance measurement accuracy can meet the target approach and principle task requirements from 11 km to 20 m.
