The results show that double dwells mode is superior to single dwell mode. Finally, PN code periode that is available for short wave SFH/MFSK system is determined by numerical simulating, and average acquisition time is also evaluated. 短波 慢跳频 PN码 串序捕获 单、双驻留 short wave slow FH PN code serial acquisition single and double dwell TN914.3;TN914.4 国家自然科学基金,国防预研基金 1998-01-01 2021-04-01 1
