Abstract

Abstract:

A new array optimization algorithm for the MIMO radar is proposed. First, a minimum number of physical sensors are used to get as many virtual sensors as possible, so the physical sensors efficiency is maximum; and then the virtual array of the MIMO radar is subject to a minimum redundancy array, so the resolution of the MIMO radar system is improved and the high side-lobe levels are reduced. Theoretical analysis indicates that the array of the MIMO radar optimized by the algorithm in this paper is an NLA with its elements both for receivers and for transmitters. With the same number of physical sensors, the MIMO radar in this paper can improve the ratio of mainlobe to sidelobe of the beampattern compared with other MIMO radar array geometries. Some numerical examples are simulated to verify the effectiveness of the algorithm.
