Performance enhancement of nulling antennas by utilizing the concept of multiplicative array
TL;DR: In this article, a beam forming architecture for improving the power-inversion algorithm that is most commonly used in nulling antenna systems is proposed, where the received signals from the physical radiation elements in digital domain are multiplexed with a power inversion array (PIA) and a primitive array (PA), and then form the desired radiation pattern by multiplying the outputs from PIA and PA, to obtain expected narrow nulls in the directions of the interference and roughly maintain the original gain and the beam shape of the main lobe.

Influence of the solar hydrogen Lyα line on the GNSS signal delay in the ionospheric D-region
TL;DR: In this article , the influence of changes in the solar hydrogen Ly α radiation, which is manifested in variations of the D-region electron density and, consequently, the total electron content in this region, on the propagation of the Global Navigation Satellite System (GNSS) signals was investigated.
