摘要 MIMO雷达是近几年来发展起来的一种新体制雷达,由于采用空间分集与信号分集技术,相对于传统相控阵雷达在目标检测及参数估计性能都有很大提高。文中主要研究MIMO雷达的系统的自适应数字波束形成算法,介绍了基于MIMO雷达的SMI自适应DBF算法,该算法有较好的性能,易于实现。针对于空间中的有源干扰,从自由度的角度讨论分析了MIMO雷达处理系统中自适应模块的位置问题。 The multiple-input multiple-output（MIMO） radar is a new radar system developed in recent years.Since space diversity and signal diversity technology is used,the MIMO radar＇s capability of target detection and parameter estimation has been improved significantly comparing with the conventional phased array radar.An adaptive digital beamforming algorithm for MIMO radar system is studied.SMI adaptive DBF algorithm based on MIMO radar is presented.This algorithm has perfect performance and is easily implemented.In view of active jamming in space,the position problem of adaptive module in MIMO radar system is analyzed from degree of freedom.
