Description
fbdown=fr+fd (2)
また、ドップラ周波数fdと速度Vとの関係は次式(3)で表される。
このfbup、fbdownを減算処理などで飛行時間により生じる周波数差frを算出し、fbup、fbdownを加算処理などでドップラシフト分のずれfdを算出し、それらに定数を乗算することにより距離、及び相対速度に変換することができる。即ち、fr及びfbは、それぞれ次式(4)及び(5)で表される。
fd=(fbup+fbdown)/2 (5)
したがって、同一の物標に関して、fbup、fbdownの両者が求められれば、fr、fdが算出でき、物標の距離及び相対速度を検出することができる。なお、物標との相対速度が0の場合には、アップビート区間でのビート信号周波数fbup及びダウンビート区間でのビート信号周波数fbdownは等しくなる。
