DRFM technology for storing and modulating radio frequencies with ideal quadrature processing requires digital processing (DP) costs: sampling frequency, speed, bit depth and is often difficult (naturally) compatible with the requirement to take into account resource constraints (hardware, computing, consumption). Significant difficulties in quadrature signal processing appear in the case of memorizing the electromagnetic field (EMF) at discrete points − in multichannel (multielement) systems that take into account spatial frequency (DRFM-S technology) and polarization (DRFM-SP technology) features. To reduce the influence of the DP quantization and sampling effects, an important role is played by the real and imaginary components quadrature transformationmodels in the construction of demodulators and modulators in multichannel (multielement) DRFM information systems operating in adaptive modes.
