摘要
Bekermani提出了一种新的空时编码方法,用于雷达或声纳等目标检测和定位系统,该方法将数字波束形成同时应用于天线阵元发射端和接收端。在此基础上,将该方法推广至多目标定位系统,利用该方法可以产生大量虚拟阵元,从而增加了可以检测到的目标数目,提高了阵元的利用率。通过计算机仿真,证明该方法的可行性。
A new space - time coding configuration for target localization by radar or sonar systems is proposed, which allows the digital steering of the beam pattern in both transmit and receive mode. This configuration model is extended to the multiple targets localization with many virtual sensors obtained, thus increasing the numbers of detectable targets. Computer simulation proves the reliability of this method.
