| 摘要: |
| 相控阵技术的引入驱动了测控系统的发展，大大提升了系统的功能和性能，同时也带来了一些新的技术问题。相控阵测控系统中存在着角误差耦合效应等特殊问题，这会增大测速/测距误差。为了解决这一问题，采用了附加误差法、基准阵元法和相量法来分析测控系统相控阵化后产生的测速/测距附加误差，同时探讨了附加误差的各种误差源及其产生机理，并推导出了相应的测速和测距附加误差的表达式，为有关的精度分析和减小附加误差的技术途径提供了理论基础。 |

| Abstract: |
| The introduction of phased array technology has promoted the development of TT&C systems,greatly improving the functionality and performance of TT&C system.However,it has also brought about some new technical problems.Some special problems such as the angle error coupling effect in phased array TT&C systems will increase velocity /range measurement errors.To solve the problem,the additional error method,reference array element method,and phasor method are used to analyze the additional velocity and range measurement error generated by the phased array of TT&C system.Various sources and generation mechanisms of additional errors are explored,and expressions for additional errors of velocity and ange measurement are derived,which provides a theoretical basis for accuracy analysis and technical approaches to reduce additional errors. |
