摘要:

最近提出的基于矩阵完成的多输入多输出雷达(MIMO-MC)采用稀疏采样来减少需要转发到雷达融合中心的数据量,并且因此能够节省通信功率和带宽。本文提出的设计,优化MIMO-MC雷达和通信系统之间的频谱共享,使后者最小限度地干扰前者。首先,通信系统的发送协方差矩阵的设计,以最小化有效干扰功率(EIP)的雷达接收机,同时保持一定的平均容量和发送功率的通信系统。提出了两种方法,即非合作和合作的方法,后者是适用于当雷达采样方案是已知的通信系统。其次,提出了通信发射协方差矩阵和MIMO-MC雷达采样方案的联合设计,进一步降低了EIP。

英文摘要:

Recently proposed multiple input multiple output radars based on matrix completion (MIMO-MC) employ sparse sampling to reduce the amount of data that need to be forwarded to the radar fusion center, and as such enable savings in communication power and bandwidth. This paper proposes designs that optimize the sharing of spectrum between a MIMO-MC radar and a communication system, so that the latter interferes minimally with the former. First, the communication system transmit covariance matrix is designed to minimize the effective interference power (EIP) to the radar receiver, while maintaining certain average capacity and transmit power for the communication system. Two approaches are proposed, namely a noncooperative and a cooperative approach, with the latter being applicable when the radar sampling scheme is known at the communication system. Second, a joint design of the communication transmit covariance matrix and the MIMO-MC radar sampling scheme is proposed, which achieves even further EIP reduction.
