Definitions

  • the transmission circuit 5 comprises a transmission path 5i for each element 2 i of the network 2 and makes it possible to route a signal s' i to be transmitted by the elements 2 i of the 2.
  • the processing of each transmission channel 5i comprises, as is known, a digital / analog conversion stage 12, a carrier frequency passing stage 13, a distribution stage 14 through Buttler matrices, an amplification stage, a filtering stage 16, a stage 17 of recombination through Buttler matrices and a stage 18 of frequency diplexing.
  • sensors 10 1 , 10 2 , ..., 10 j , ... 10 M measuring the near field radiated by the elements 2 i M can be different from N and is generally greater than the number N of elements 2 i .
  • the system could only work in transmission.
  • the index i refers to the elements used in reception, less than or equal to the number N of elements of the network 2
  • k refers to the elements used in transmission, less than or equal to the number N of elements of the network 2.
