Abstract: A method for providing correction values for phase based measurements. Where averaging techniques are employed for exploiting redundancy in multiple measurements, by constraining the phase ambiguity in a correction value to be an integer multiple of the carrier wavelength, carrier phase based measurements can be used.
Abstract translation: 一种用于提供基于相位的测量的校正值的方法。 在采用平均技术来利用多个测量中的冗余的情况下，通过将校正值中的相位模糊约束为载波波长的整数倍，可以使用基于载波相位的测量。

Abstract: A layer of open cell polyurethane foam adhered to a layer of a non-woven fibrous material of fine porosity relative to the foam results in an efficient fluid (e.g., air) filtering medium having a high capacity for retaining particulate contaminants. The combined layers are useful as an air filter element.
