基于单通道MIMO雷达的毫米波安检成像
Millimeter wave security imaging based on single-channel MIMO radar
摘要
Abstract
Millimeter wave(mmW)multiple-input multiple-output(MIMO)radar is state-of-the-art technique for security imaging.However,the exploitation of large number of transmit/receive channels leads to much high-er cost and complexity for the MIMO radar than that of the single-channel radars.Aiming for developing the low-cost and low-complexity mmW MIMO security imaging radar,dual-code-division-multiplex(dual-CDM)tech-nique has been proposed in this paper.It is worth noting that the proposed method can realize the similar imaging performance with the traditional multi-channel MIMO radar by a single transmit/receive channel,which is of great significance for the development and application in the area of security imaging.Moreover,the de-multi-plex code,which can attain the maximum code diversity gain against the interference,is designed based on mis-matched filter theory.Finally,both the numerical and the experimental results are provided to verify the correct-ness and the validity of the proposed methods,which shows that quite a satisfactory imaging performance is achieved.关键词
