Abstract

Attribute to the problem that the existing radar system errors estimation algorithm is complex and the inherence relationship between the errors and the factors that caused the errors is hidden, a convenient arithmetic for radar system errors calculation is proposed in this paper. The main contributions of this paper are that, the less sensitive one is found and ignored among the factors, and an errors-function of these remained sensitive factors is obtained. Firstly, the spherical stratification method is introduced, and the errors are turn out to be affected by the range and elevation between target and radar, as well as the altitude of radar. Secondly, by a numerical simulation, the altitude is proved to be less sensitive to the errors. Lastly, an errors-function with respect to these much more sensitive factors is obtained by polynomial fitting. As a result, the computational cost is greatly reduced. The simulation results show that the proposed method can estimate the radar errors with high precision.
