Abstract

In order to realize high resolution location estimation by using array radar, it is necessary to increase the number of elements. However, it is often difficult because of the cost. We have shown that the number of virtual array elements can be effectively increased by using the MIMO radar with Minimum Redundancy Array (MRA) by the Khatri-Rao (KR) product virtual array processing. However, the optimum arrangements to realize a largest virtual Uniform Linear Array (ULA) is still unclear. In this paper, we have shown the optimum element arrangements that make a virtual ULA when we apply the KR product virtual array processing to MIMO radar.
