| Abstract: |
| For a problem of the digital guidance jumping dot on the automatic tra
cking antenna, the calculating procedure of the satellite orbit forecast based o
n t
he analytical method is presented around a typical digital guidance algori
t
hm of a certain shipborne radar. Then with some instances, the real cause for su
ch a problem is found according to the opposite calculating procedure usi
ng simulation graph and a check-up means uniting the static test with the dynami
c
test,that is the first order short-term item. The problem is solved completely
by giving an angle limit on dimensional geometrical conn
ection. |
