摘要
根据现代协作作战的要求,设计了一种由地面基站或异平台发射的载有方向信息的新型制导信号。发射阵选用8元稀疏阵列,利用信号空间特性,发射一种方向调制的MT-CDMA制导信号。弹体不主动发射信号,只要采用单天线接收技术和码片内多径分量分离技术,便能确定弹体以及目标的方位,实现静默制导和攻击。文中详细阐述了信号设计与接收算法,仿真了简单测角性能。
To meet the requirement of modern cooperative combat,this paper proposes a guidance signal transmitted by a sparse array with eight elements from the ground base or different platforms.The signal utilizes the spatial characteristics of the sparse array to transmit MT-CDMA bearing azimuth angle information.The advantage of this signal is that a missile can realize silence guidance and attack because the missile only need receive the signal by a single antenna and employ the technology of multi-path separation to determine the azimuth angle information of the missile and target.The design scheme and receive algorithm of the signal are presented in detail and the direction finding performance is also investigated to verify the feasibility and effectiveness of the signal.
