The Doppler shift is due to the component of motion of the object in the direction of the transmitter, plus the component of motion of the object in the direction of the receiver. Equivalently, it can be considered as proportional to the rate of change of bistatic range. In a bistatic radar with wavelength ''λ'', where the distance between transmitter and target is ''Rtx'' and distance between receiver and target is ''Rrx'', the received bistatic Doppler frequency shift is calculated as: :$f\; =\; \backslash frac\backslash frac(R\_+R\_)$ Note that objects moving along the line connecting the transmitter and receiver will always have 0 Hz Doppler shift, as will objects moving around an ellipse of constant bistatic range. ==See also== * Bistatic radar * Passive radar 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「Bistatic Doppler shift」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
