摘要：The invention relates to a method for humidity and/or density measurement ina sample material, using a microwave transmitter, a microwave receiver and an analyticalunit which can determine the phase and amplitude of microwave radiation from the
microwave transmitter received by the microwave receiver and n which a complextransmission function for the measuring arrangement can be stored. Said methodcomprises the following steps: the phase and amplitude are determined for a number offrequencies of the microwave radiation transmitted through the sample material, usingthe complex transmission function for the measuring arrangement the complextransmission function sample material is calculated from the determined values andtransformed into the time domain as a complex time domain function, the maximum valueof the main pulse is determined as parameter A from the time domain function, the widthof the main pulse is calculated as parameter B from the time domain function and/or theamplitude value for the main pulse is determined as parameter H and a humidity and/ordensity of the sample material is determined based on the parameter A and theparameter B and/or H.
