| Abstract(J) | 本研究では，ミリ波レーダの性能を向上する信号処理技術を提案する．2017年からTime Division MIMO方式チップが普及したが，この方式には速度ダイナミックレンジが数分の1に縮小する欠点があった．そのため最近では速度ダイナミックレンジが広いDoppler Division MIMO方式へ移行しつつあるが，この方式にも自己混信スペクトルを分離するという難題がある．そこで筆者等は，FFTを2～3次元のMatcing Pursuit法に置き替えることで，Time Division MIMO方式の速度ダイナミックレンジの大幅拡大を実現した． Translation |
| Abstract(E) | In this paper, a new signal processing technique, which improves performance of Millimeter-wave radar, is proposed. Since 2017 radar chips with Time Division MIMO function are widely available, but this technology has a drawback of reduced dynamic range of velocity. So the recent trend is obviously moving to another technology, Doppler Division MIMO, but it also has a drawback of self-interference in the spectrum. Authors has replaced FFT with 2-3 dimensional Matching Pursuit algorithm, and has successfully enlarged dynamic range of velocity. |
