| Research Abstract |
In this research, the method of relative position detection oftransmission and reception terminals, i.e. realization of a multi-input-multi-output (MIMO) radar, has examined by using the MIMO system which carries multi antenna elements in both terminals. As a problem, when many terminals existed, or when a multipass wave existed, many interference waves will enter into a receiving side, and it was predicted that the position estimate became difficult. Then, the technique of the position estimate of the terminals was developed by using the broadband signals. The broadband signal is divided into multi narrow band signals. Then, a conventional direction of arrival estimation method is adopted by rising from low frequency without the influence of a grating robe to the high frequency from which high resolution is obtained
