摘要

A process for the free space - radio signal measurement with a radio transmitting unit (3) with a transmitting antenna (12), a separate radio reception of a unit (4), the at least one measurement antenna (5) and connected to a radio receiver (7), and with a position detecting means (6), wherein the at least one measurement antenna (5) or the transmitting antenna (12) by means of a floating platform (2) is brought to a measuring position,characterized in that– the at least one measurement antenna (5) or the transmitting antenna (12) during a measuring period, without leaving the measuring position is moved by the floating platform,– a of the radio transmitting unit (3) via the transmitting antenna (12) in the electromagnetic signal emitted during the measuring period, the far field via the at least one measurement antenna (5) and the radio reception of a unit (4) in the form of a band pass signal is measured,– during the measuring period, a plurality of measured values of the band pass signal is detected,– the measuring position by means of the position detecting means (6) is detected,– the absolute field strength of the transmitted signal from the measurement position and the plurality of measured values of the band pass signal is determined by one or several maximum values of the carrier amplitude of the band pass signal from the plurality of measured values are determined and the absolute field strength proportional to the maximum value, or the maximum values is determined, and– Disturbances of the of the transmitting antenna (12) for the measurement antenna (5) transmission channel is formed from the measurement position and the plurality of measured values of the band pass signal is determined by the steps of:– Determination of useful - and undesired signal components and their field strengths of the detected measured values of the band pass signal,– Comparison of the determined wanted - and interference signal components and their field strengths with the results of at least one numerical simulation of electromagnetic waves in the transmission channel,– Decision, whether at least one fixed with respect to the matching criterion match ..
