子带阵列处理技术的导航抗干扰终端设计与实现

Design and Implementation of Navigation Anti-jam Terminal Based on Subband Array Processing Technology

基于子带阵列处理技术的导航抗干扰终端要求多天线单元、多通道接收,这与信息化条件下军事需求的终端机动性强、体积小、重量轻是相矛盾的。为此提出了基于子带阵列处理的数字波速形成(DBF)抗干扰终端实现结构,满足DBF数字接收机系统实时性和抗干抗要求,同时可以灵活在资源消耗和传输速率间折衷考虑,并且易于在高速FPGA上实现。

Navigation anti-jam terminal based on subband array processing technology requesting multi-antenna unit,multi-channel receiver,which is contradictory with the military needs under the informatization condition.The information terminal high mobility,small size and light weight.To this end,the paper proposed a digital beamforming（DBF） anti-jam terminal structure based on sub-band array processing technology,which meet the needs of real time and anti-jam of the DBF digital reciver requirements,mean while allowi the flexibility between resource consumption and transmission rate in a compromise between consideration.So this terminal has strong controllability and can be achieved easily in high-speed FPGA.
