Dwell time (''TD'') in surveillance radar is the time that an antenna beam spends on a target. The dwell time of a 2D–search radar depends predominantly on * the antennas horizontally beam width ''θAZ'', and * the turn speed ''n'' of the antenna (in rotations per minute or rpm, i.e. 360 degrees in 60 seconds = multiplied by a factor of 6). Dwell time is calculated by: : ==References== 〔 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Dwell time (radar)」の詳細全文を読む スポンサード リンク
