System for vector measurement of the electromagnetic field intensity consisting of two microwave generators (1) and (11) with coherent signals with the option to set at their outputs the phase shift and magnitude of these signals. The output of the first microwave generator (1) is connected to the input of the transmitting antenna (4) of the testing channel and the output of the second microwave generator (11) is connected to the transmitting antenna (6) of the reference channel. Another option is that one microwave generator (1) is used and its microwave output is connected to the input (31) of the power splitter (3) while the first output (32) of the power splitter (3) is connected to the input of the transmitting antenna (4) of the testing channel and the second output (33) of the power splitter (3) is connected to the input of the block (5) controlling the phase and/or magnitude, the output of which is connected to the transmitting antenna (6) of the reference channel. Electromagnetic field radiated by the transmitting antenna (4) of the testing channel comes to the receiving antenna array (8) or to the examined object (7), from which it is reflected, passes through it or is dispersed, and subsequently it comes to the receiving antenna array (8) that is simultaneously radiated by the electromagnetic field generated by the transmitting antenna (6) of the reference channel. |
