The present-day ocean remote sensing instruments that operate at low microwave frequencies are limited in spatial resolution and do not allow for monitoring of the coastal waters. This is due to the difficulties of employing a large reflector antenna on…

This paper presents the latest status of the full-wave simulation of MetOp-SG Ice Cloud Imager (ICI) and the methodology proposed to correlate both simulation and antenna pattern testing in two cases, namely for the main beam and the full 4π….

Beam squint in single offset reflector antennas with circularly polarized feeds is well known. For applications where single offset reflectors operate in orthogonal circular polarizations in Tx/Rx, the beams in the two bands squint in opposite directions resulting in incongruent…

The traditional O(f6) computational time scaling when using Method of Moments for monostatic Radar Cross Section calculations is circumvented by applying the Multi-Level Fast Multipole Method (MLFMM) along with a number of modifications. The performance of the modified MLFMM-based algorithm…

Surface shaping of reflector antennas for creating a contoured beam is an ubiquitous task in the design of modern communication satellites. In this paper, we highlight two major improvements to the state-of-the-art that provides a major increase in computational efficiency…
