System for vector measurement of electromagnetic field intensity

摘要

The present invention relates to a system for vector measurement of electromagnetic field intensity comprising two microwave generators (1) and (11) with coherent signals and with a possibility to set a phase shift and amplitude of these signals at the generator outputs. The output of the first microwave generator (1) is connected to the input of a transmitting antenna (4) of a testing channel and the output of the other microwave generator (11) is connected with a transmitting antenna (6) of a reference channel. Another possibility is the use of only one microwave generator (1), having its microwave output connected to the input of a power divider (3) having its first output (32) connected to the input of the testing channel transmitting antenna (4) while the second output (33) of the a power divider (3) is connected to a phase and/or amplitude control block (5) having its output connected to the reference channel transmitting antenna (6). Electromagnetic field emitted by the testing channel transmitting antenna (4) irradiates a series of receiving antennas (8) or irradiates the object being investigated (7) from which it reflects, passes through or dissipates and subsequently irradiated the series of receiving antennas (8) being at the same time irradiated by the electromagnetic field emitted by the reference channel transmitting antenna (6).
