Abstract :
MIMO radar and Khatri-Rao (KR) product virtual array are the methods for increasing angular resolution of the array radar. The KR product is not suited to radar because KR product needs data property of uncorrelated wave incidence. However, when we extract responses of moving targets having different Doppler frequencies by Doppler filtering, the KR product array works almost properly because their correlation become low. In this report, we show the availability of the MIMO radar with the KR product virtual array for indoor location estimation by experiment.
