Outline of Final Research Achievements

Target-sensing techniques with high resolution and high efficiency have been researched and developed so that MIMO (Multiple-Input Multiple-Output) radar can detect both the position and extension of the targets. In this research, signal transmission diversity schemes are utilized which consist of code spreading and multiple beamforming compositely. As a result, it is confirmed that the DOA (direction-of-arrival) estimation accuracy of incoming far-field waves is improved and we can obtain the angular spread of each incoming far-field wave simultaneously. Moreover, the method features direct calculation with high efficiency. For the near-field source localization, our estimation method is improved continuously. In addition, the calibration method for array antenna is devised and its effectiveness is confirmed.
