| Outline of Final Research Achievements |
The main objective in this research was a realization of human detection in multipath indoor environment by using MIMO Doppler radar. The indoor human location estimation has been considered as a serious problem because of strong multipath by the wall and so forth. In this research we constructed the MIMO Doppler radar based on Linear FM, and demonstrated that micro-Doppler effect caused by the motion of human can be clearly detected and extracted. This enable us to discriminate human echo and multipath echo. In addition, we proposed a new virtual array technique based on the MIMO and Khatri-Rao processing. This technique can further enhancement of effective array length hence angular resolution can be improved.
