PROCEDURE MEASURING INTENSITY OF ELECTROMAGNETIC FIELD OF RADIO SIGNALS AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2002 - IPC

FIELD: radio engineering, radio control systems measuring intensity of electromagnetic field of radio signals. SUBSTANCE: procedure includes simultaneous reception of signals by array comprising N elements with number P of formed groups of pairs. Complex amplitudes of pairs are obtained by convolution of complex of conjugate amplitudes of signal for P pairs of signals. They are used to carry out P two-dimensional Fourier transforms to obtain P components of two-dimensional angular spectrum. Two-dimensional angular spectrum is obtained by their multiplication. Maximal modulus of component of actual part of two-dimensional angular spectrum is exposed and is employed to pass judgment on intensity of electromagnetic field of radio signals. Device for implementation of procedure has array, calibration generator, antenna switch, two-channel receiver, analog-to-digital converter, Fourier transform unit, storage, convolution computer, former of antenna radiation patterns, units determining amplification factor of receiver, field intensity calculator and generator of synchropulses. EFFECT: provision for measurement of intensity of electromagnetic field of radio signals. 4 cl, 4 dwg
