Experimental investigation of single pulse matched filtration on the spin-wave active ring resonator

Abstract

Abstract Experimental investigation of single square pulse matched filtration in the active ring resonator is described in this work. Features of spin-wave delay line with metal screen in the active ring resonator are discussed. Influence of the microwave amplifier on formation of the active ring resonator impulse response was described. It is shown that the side peaks of impulse response depend on full energy in the ring circuit. Measurements of the ring response on input mixed signal with high S/N ratio are presented. Dependence of the output signal amplitude on signal to nose ratio is showed and discussed. Formation of the noise part of output signal is showed and influence of spin-wave dispersion on it is described.
