Optical frequency modulation continuous wave coherent laser radar for spacecraft safe landing vector velocity measurement

摘要：

　　The design and performance of Optical frequency modulation continuous wave (OFMCW) coherent laser radar is presented.By employing a combination of optical heterodyne and linear frequency modulation techniques and utilizing fiber optic technologies, highly efficient, compact and reliable laser radar suitable for operation in a space environment is being developed.We also give a hardware structure of the OFMCW coherent laser radar.We made a detailed analysis of the measurement error.Its accuracy in the speed range is less than 0.5%.Measurement results for the movement of the carrier has also made a detailed assessment.The results show that its acceleration vector has better adaptability.The circuit structure is also given a detailed design.At the end of the article, we give the actual authentication method and experimental results.
