| Abstract: |
| For checking capability and performance of antenna servo feedback system, the s
imulation of angle tracking signal is needed. Based on the relationship between
angle offset in directional diagram and sum-difference signal amplitude,changing
angle offset can realize dynamic simulation of angle tracking characteristics.
In this paper,angle simulation implementation method is introduced,the factors
influenci
ng simulation precision are analysed.Engineering application verifies
the feasibility of the proposed method. |
