摘　　要：现代战争要求雷达、电子战、通信、导航、探测等各种任务系统具备在同一个作战平台中同时工作的能力,当前的平台架构尚不能很好地满足这一需求。对此,提出一种模块化多功能同时收发阵列架构,该架构每个天线单元可以在发射和接收状态间切换,并通过引入额外的发射观察通道和接收抵消通道,实现自干扰的多层级抑制和消除,为解决大型阵列上多通道间同时收发难题提供了参考,有助于推动实现同时多功能作战应用。Modern warfare demands various mission systems should be capable of operating simultane-ously within the same combat platform such as radar,electronic warfare,communication,navigation,detec-tion,etc.Current mission platform cannot adequately meet this requirement.This work proposes a modular multifunctional simultaneous transmit and receive array architecture,in which each antenna element can switch between transmit and receive states.By introducing additional transmit observation channels and re-ceive cancellation channels,the architecture achieves multi-level suppression and elimination of self-in-terference,providing a reference design for solving the problem of simultaneous transmit and receive among multiple channels in large arrays.It also helps to promote the realization of simultaneous multifunc-tional combat applications.
