Target Detection for Synthetic Aperture Radiometer Based on Satellite Formation Flight [PDF]

open access: yesSensors, 2023
Synthetic aperture interferometers formed by satellite formations have been adopted to improve spatial resolution. Due to the limited number of satellites and limited integrated time, the use of sparse baselines can result in distorted reconstructed ...

Motility mediates satellite formation in confined biofilms. [PDF]

open access: yesISME J, 2023
Abstract Bacteria have spectacular survival capabilities and can spread in many, vastly different environments. For instance, when pathogenic bacteria infect a host, they expand by proliferation and squeezing through narrow pores and elastic matrices.

The data of establishing a three-dimensional culture system for in vitro recapitulation and mechanism exploration of tumor satellite formation during cancer cell transition [PDF]

open access: yesData in Brief, 2017
Tumor satellite formation is an indicator of cancer invasiveness and correlates with recurrence, metastasis, and poorer prognosis. By analyzing pathological specimens, tumor satellites formed at the tumor-host interface reflect the phenomena of ...

Satellite Formation around the Largest Asteroids

open access: yesThe Astrophysical Journal Letters
Satellites around large asteroids are preferentially found among those with the most rapid rotation and elongated shape. The taxonomic statistics are similarly skewed; in total, 13 asteroids larger than 100 km are known to have satellites, but none have ...

Optimal On-Orbit Inspection of Satellite Formation

open access: yesRemote Sensing, 2022
In a formation-flying mission where multiple spacecraft must cooperate and maintain a prescribed relative separation, the early detection of possible anomalies is a primary requirement.

Along-Track Multistatic Synthetic Aperture Radar Formations of Minisatellites

open access: yesRemote Sensing, 2020
The paper analyses an along-track multistatic Synthetic Aperture Radar (SAR) formation. The formation aims at achieving a high azimuth resolution maintaining at the same time a large swath width. The case with one transmitting sensor and all receiving is

Satellite Cluster Formation Reconfiguration Based on the Bifurcating Potential Field

open access: yesAerospace, 2022
The satellite cluster formation reconfiguration has received considerable attention in recent years. However, the traditional centralized control methods are challenging to apply to satellite clusters because of the enormous fuel consumption, and few ...

Exploring the Recycling Model of Phobos Formation: Rubble-pile Satellites

open access: yesThe Astronomical Journal, 2023
Phobos is the target of the return sample mission Martian Moons eXploration by JAXA that will analyze in great detail the physical and compositional properties of the satellite from orbit, from the surface, and in terrestrial laboratories, giving clues ...
