TL;DR: The experimental results confirm expected characteristics of near-nadir Ka-band interferometric SAR imagery, such as strong water/land radiometric contrast and very highInterferometric coherence on water.

TL;DR: In this article, a method for the optimization of the power-added efficiency (PAE), as well as the error vector measurement (EVM) of a 20-GHz power amplifier applied in this case to the M quadrature and amplitude modulations is presented.

TL;DR: In this paper, the suitability of using a multiport amplifier (MPA) for a power section of space telecommunication payloads with power flexibility requirements is discussed, and the performances of an MPA-based architecture are compared to those of a classical amplification architecture having one power amplifier per beam.

TL;DR: In this paper, a technique for predicting odd-mode parametric oscillations from the analysis of exact pole-zero cancellations that take place in the frequency response obtained at some specific nodes of power amplifiers is presented.

TL;DR: The rationale of this paper is to assume that SWOT's scientific requirements are met on all errors but the ones being cross-calibrated, and they are able to deal with higher error levels (e.g., if hardware constraints are relaxed and replaced by additional ground processing).
