| Abstract: | With the extensive application of GNSS receiver to martial field, against inter- face of signal becomes essential in the navigation war. The effect on the receiver＇s acquisi- tion and tracking performance is analyzed, three kinds technique of interface suppression such as time, adaptive adjustment to zero and space-time association are verified in different interface settings. Scheme and parameter settings are crucial to process capability and imple- ment cost of hardware. The research conclusion provides theory guidance to manufacture project machine and boost up battle efficiency of weapon in the complicated electromagnetism environment. |
