Range Vernier technique is a novel phase ranging technique, which can provide radial measurement with noise values at sub-qtr-wavelength level. 游標測距技術(shù)是一種新穎的相位測距方法，該技術(shù)可以提供精密的徑向距離測量值，其隨機誤差小于四分之一波長(cháng)。
The design of the range finder is targeted on high precision and little blind area. 超聲測距儀表的設計以達到高精度小盲區為目的。
As the range dropped to four thousand, the option to surface was dimming. 等到測距降到四千碼的時(shí)候，升上水面的機會(huì )就暗淡了。
