摘要：【課題】ドップラ分割多重を利用するレーダ装置において、受信信号から複数の送信信号を識別する精度を向上させる。【解決手段】送信アンテナ部3は、M個の送信アンテナを有する。変調部22は、発振部21が発生させた共通信号をM個に分岐し、それぞれが異なる位相回転量で、繰返周期毎に分岐信号の位相を回転させる位相偏移変調を行うことで、各送信アンテナに供給するM個の送信信号を生成する。受信アンテナ部4は、N個の受信アンテナを有する。処理部6は、受信アンテナ部4で受信されたN個の受信信号のそれぞれから抽出される、各送信信号に対応したM個の信号成分に基づいて送信アンテナ部3からの放射波を反射した物体に関する情報を生成する。送信アンテナの数Mは、位相偏移変調に用いられる位相数をPとし、P>Mに設定される。【選択図】図1

摘要： A smart antenna steering algorithm performs a periodic re-scan at an end of a sustained use period and before a next sustained use period. During a sustained use period, a re-scan of the other antenna beams is not performed. The periodic re-scan is performed on alternate antenna beams that were selected when the preferred antenna beam was selected. The steering algorithm monitors a quality metric of the alternate antenna beams as well as a quality metric for the preferred antenna beam. If the quality metric of the preferred antenna beam is less than the quality metrics of anyone of the alternate antenna beams, then the alternate antenna beam corresponding to the quality metric having a higher value is selected for the next sustained use period.

摘要： PROBLEM TO BE SOLVED: To realize the miniaturization and the low cost of a phased array antenna. SOLUTION: A transmission signal output by a transmission signal outputting portion 11 is given to a transmission antennas 21 to 24 through demultiplexers 12 to 15 and phase shifters 16 to 18. The electric length of each of the phase shifters 16 to 18 is fixed, and a phase shift quantity of each of the phase shifters 16 to 18 is not changed. When the direction of a radio wave beam is deflected on the combined wave front of the transmission signal emitted from the transmission antennas 21 to 24, the frequency of the transmission signal output by the transmission signal outputting portion 11 is changed by a control signal from a control apparatus 28. Phases of the transmission signal radiated by the transmission antennas 21 to 24 are shifted by turns, and a travelling direction of the radio wave beam is deflected. COPYRIGHT: (C)2006,JPO&NCIPI
