Spaceborne synthetic aperture passive imaging technology for wide-area electromagnetic spectrum map generation.
Article in iScience, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Current space-based electromagnetic spectrum sensing and imaging methods suffer from several limitations, including low efficiency in acquiring holistic situational information of radiation source clusters, inherent contradiction between field of view (FOV) and resolution, and insufficient real-time imaging capability. To address these challenges, this paper innovatively applies the synthetic aperture passive imaging method, originally used in the field of "natural thermal radiation remote sensing," to the domain of spaceborne electromagnetic spectrum sensing, establishing a system model encompassing "ground station modeling - space propagation - spaceborne synthetic aperture passive imaging," and analyzing the differences between the ground station signal and natural thermal radiation during model establishment and synthetic aperture imaging processes in detail. We adopt a staggered Y-shaped synthetic aperture and define its placement and imaging perspective when deployed on a satellite platform. The experiments establish a dynamic simulation scene achieving a high-precision, wide-area, real-time rapid imaging of ground station electromagnetic situation.
