| 摘 要： | 针对信息化弹药引信受到体积、功耗等条件限制,导致现阶段弹载指令传输是基于窄带调制传输,其抗干扰、多址等性能不理想。提出应用直接序列扩频通信方式进行指令信息传输来提高了战场环境下的抗干扰能力。重点针对单频大功率干扰、宽带干扰进行抗干扰分析,并且提出在频分的基础增加码分+时分的多址方式将在一个频点上的地址数增加到96,大大提高了弹药指令信息传输系统的性能。

| Abstract: | Nowadays the transmission of cannon-carried instruction is based on narrowband modulating transmission,which is not perfect in some aspects such as anti-jamming,multiple access and etc,due to the restrictions of bulk and power-consuming of information-based ammo fuze.Direct sequence spread spectrum(DSSS) communication methods to transmit instructing information is put forward to use.After doing some anti-jamming analysis of high-power jamming with single-tone and broad band jamming,a notion is presented tha... |
