| Abstract: |
| A satellite communication anti-jamming design combing direct sequence spread spe
ctrum(DSSS) and adaptive nulling antenna is proposed. For different jamming cond
itions and satellite transponding modes, theoretical analysis of system anti-jam
m
ing performance is given. It is concluded that the system anti-jamming capabilit
y can be effectivly improved by combining DSSS and adaptive nulling antenna and
then performing onboard regeneration processing and transponding. |
| Key words: satellite communication anti-jamming DSSS adaptive nulling jamming tolerance |
