Low angle estimation in MIMO radar based on unitary ESPRIT under spatial smoothing
IET Radar, Sonar & NavigationAiming at the problem that the overlapping of multipath signals seriously affects the radar's performance of the elevation angle estimation for low‐altitude targets, the authors combine the unitary ESPRIT (UESPRIT) and the multi‐input and multi‐output ...

Energy Science &Engineering, EarlyView.This study aims to conduct a performance comparison of irradiation and temperature on different commercially available PV modules like PPVM, MPVM, LPVM, and BPVM. Here, the TPVM is not considered in the analysis due to its toxic nature. This study has considered the LPVM because researchers have not focused on it due to the higher area requirement for ...

Design of a Hydroelectronic Solar‐Tracking System for Solar Panels
Energy Science &Engineering, EarlyView.A prototype of a passive solar‐tracking system utilizing buoyant force based on water level was developed, and its MATLAB/Simulink model was implemented. This study is expected to encourage researchers to design solar‐tracking mechanisms using metals with different thermal expansion coefficients, air, oil, and other fluids. ABSTRACT This study presents
