We have proposed a localization method of multiple living-bodies using MIMO (Multiple-Input Multiple-Output) radar in multi-path environments. In this method, localization of multiple living-bodies are realized by eliminating false images caused by multiple estimated directions. However, it has problem that the estimation accuracy is degraded with certain location combinations of living-bodies because false images cannot be eliminated correctly. To solve this problem, in this report, we descrive a localization method of multiple living-bodies using the MIMO virtual array. In this method, living-body locations can be estimated without false image problem by applying the DOA (Direction of Arrival) estimation method to the virtual MIMO steering vector, where fluctuating components extracted from virtual channels are used. From the measurement results, it is found that 0.40 m improvement of the estimation error in 50% value of CDF (Cumulative-Distribution-Function) is obtained by use of this method compared to the previous method when three living-bodies exist. |
