Capella Space First Operational SAR Satellite

2021 IEEE International Geoscience and Remote Sensing Symposium IGARSS, 2021
Capella Space launched its first commercial Synthetic Aperture Radar (SAR) satellite in August 2020. After commissioning phase, Capella started commercial operations in January 2021, deploying a fully-functional SAR system that demonstrates three engineering milestones: an 8-m2 deployable reflector mounted on small and agile satellite; the capability ...

Formation of MIMO SAR Mini-Satellites: Performance Prediction

2021 IEEE International Geoscience and Remote Sensing Symposium IGARSS, 2021
A coherent formation of $N$ identical SAR satellites is considered in this paper. These sensors transmit at the same time, code, and frequency with no synchronization whichever, but for the timing of the arrivals, creating a Multiple Input Multiple Output (MIMO) configuration.

Compact SAR: A flexible multimission SAR satellite

2015 IEEE 5th Asia-Pacific Conference on Synthetic Aperture Radar (APSAR), 2015
Thales Alenia Space (TAS) has started the “COMPACT-SAR” internal programme to develop a SAR satellite characterized by low cost and reduced mass while providing, at the same time, high image quality in terms of resolution, swath size, and radiometric performance.

Satellite and airborne SAR simulator

1993 IEEE South African Symposium on Communications and Signal Processing, 2002
In the design and implementation of synthetic-aperture radar (SAR) processors, it is useful to have a test data base with which to test processing algorithms and investigate parameters such as the point spread function. Simulated SAR data provides such a controlled data base. This paper reports on the generation of airborne and satellite SAR data using

Development of Compact SAR Systems for Small Satellite

IGARSS 2019 - 2019 IEEE International Geoscience and Remote Sensing Symposium, 2019
This paper presents the proto-flight model test results of X band synthetic aperture radar for small satellites with 130kg mass. The specification of SAR performance is single polarization SAR with 3m ground resolution for strip map mode. Optional 1 m ground resolution can be achieved with sliding spot light mode under condition of limited valus of ...

Launches of Pol-In-SAR satellite sensors and results of satellite tandem-SAR TanDEM-X

Proceedings of the 9th International Symposium on Antennas, Propagation and EM Theory, 2010
With the un-abating global population increase our natural resources are stressed as never before, and the global day/night monitoring of the terrestrial covers from the mesosphere to the litho-sphere becomes all the more urgent. Microwave radar sensors are ideally suited for space imaging because those are almost weather independent.

Multichromatic Analysis of Satellite Wideband SAR Data

IEEE Geoscience and Remote Sensing Letters, 2014
The multichromatic analysis (MCA) can be applied to interferometric pairs of synthetic aperture radar (SAR) images processed at range subbands and consists of exploring the phase trend of each pixel as a function of the different central carrier frequencies.

Topaz II nuclear powered SAR satellite

Space Programs and Technologies Conference and Exhibit, 1994
Abstract : The AA4871 Spacecraft Design course is the capstone class for the M.S. in Astronautics at the Naval Postgraduate School. The design team integrated a Topaz II nuclear power system with an EOS Synthetic Aperture Radar to design a low Earth orbit, three axis stabilized satellite flying in a gravity gradient stable orientation.

Design of Satellite Formations for Interferometric and Bistatic SAR

2007 IEEE Aerospace Conference, 2007
This paper deals with orbit design for formation missions aimed at interferometric and bistatic SAR observation. In particular, an analytical second order model is derived and discussed, which describes relative motion between two satellites both moving on low eccentricity orbits.
