The Multiple-Input Multiple-Output (MIMO) radar combines the signals from multiple transmit and receive elements separately to form a virtual array. Consequently, system imperfections in MIMO caused by channel imbalance mutual coupling are repeatedly present array, affecting beamforming performance. In this paper, beam pattern deviations these described mathematically relation single point targ...

This work presents an in-depth investigation of the nonlinear behavior two mutually injection-locked oscillators through inductor coupling. An analytical formulation, solved innovative procedure, facilitates understanding qualitative transformations in system solutions when increasing coupling factor. The analysis demonstrates that, a manner similar to unilaterally oscillators, families disconn...

This paper presents a new adaptive torque estimation algorithm for an interior permanent magnet synchronous motor (IPMSM) with parameter variations and cross-coupling between dand q-axis dynamics. All cross-coupled, time-varying, or uncertain terms that are not part of the nominal flux equations are included in two equivalent mutual inductances, which are described using the equivalent dand q-a...

Abstract—In this paper, the performances of thinned arrays based on Almost Difference Sets are analyzed in the presence of mutual coupling effects. The geometry under test is composed by thin dipole elements and the arising mutual interactions are modeled by means of the induced EMF method. To assess the robustness of the ADS -based thinning technique also in such a non-ideal case, an extensive...
