This paper briefly introduces the measurement requirements of aeronautical vehicles and the technical characteristics of multi-RR external measurement system. The measurement system of multi-RR system is analyzed in detail. The precision analysis of each scheme is completed. The multi-RR scheme based on three-channel independent phase- RR? System Optimization Strategy. Theoretical analysis and engineering practice show that the improved speed measurement accuracy of the measurement system will be improved and the mutual interference between the primary and secondary channels of the existing system can be overcome.
