本文用多项式逼近的最小二乘方法,从定轨要求讨论了雷达测速精度和测距精度之间应该遵循的关系。用“速距均方差比”概念,得出两者之间的合理的数量关系,从而在雷达总体设计测速精度时,给出了一种讨论的依据。
In this paper, polynomial approximation using the least square method, from the orbit requirements to discuss the relationship between radar speed accuracy and ranging accuracy should be followed. With the concept of “velocity mean square deviation ratio”, the reasonable quantitative relationship between the two is obtained, and a basis for the discussion is given when the overall velocity measurement accuracy of the radar is designed.
