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.
