A well-conceived end-to-end system should include applications undertaken for the public good as well as those driven primarily by science and commerce. The SlimSAR: A Small, Multi-Frequency, Synthetic Aperture Radar for UAS Operation Evan Zaugg, Matthew Edwards, and Alex Margulis ARTEMIS, Inc. 36 Central Ave, Hauppauge, NY 11788 Telephone: (631) 232-2424 Email: evan@artemisinc.net Abstract—The SlimSAR is a small, low-cost, Synthetic Aper-ture Radar (SAR) and represents a new advancement in high-performance SAR. The Palo Alto California-based commercial startup company Capella Space, founded in 2016 by Payam Banazadeh and William Woods, is in the process of developing a constellation of X-SAR microsatellites to provide global coverage. A small SAR system design must consider not only parametric and cost trade-offs, but also issues involving applications, data access, and data dissemination. The satellites are precursors for a planned constellation of 36 satellites. The satellites feature a 3.6 m diameter antenna of only 10 kg. Under 1-meter resolution radar satellite imaging from ICEYE breaks previous technological barriers for small SAR satellites. Left: SIR-C multi-frequency radar image (Nile) (R : CHH, G : LHV, B: LHH). ARTEMIS … Capella X-SAR (Synthetic Aperture Radar) Constellation. Iceye, the first company to launch a small SAR satellite in 2018, operates a three-satellite constellation. Synthetic Aperture Radar Systems for Small Aircrafts: Data Processing Approaches Oleksandr O. Bezvesilniy and Dmytro M. Vavriv Institute of Radio Astronomy of the Na tional Academy of Sciences of Ukraine Ukraine 1. QPS-SAR is a series of small high-resolution X-band SAR (synthetic aperture radar) earth observation satellites by the QPS Institute (iQPS). Introduction The synthetic aperture radar (SAR) is consider ed now as the most effective instrument for producing radar images of ground scenes with a high spatial resolution.

Iceye plans to begin selling interferometric data products later this year. It can distinguish objects 1 meter long and identify cars on the road. Many of the potential applications cited by Evans et al. SAR Principle A synthetic aperture is produced by using the forward motion of the radar.
Helsinki, FINLAND – August 9, 2019 – ICEYE, the global leader in small satellite synthetic-aperture radar (SAR) technology, is the first in the world to achieve better-than 1 meter resolution imagery from under-100kg (220 pounds) SAR satellites. NASA has been using it since the 1970s to detect sub-meter changes to the Earth’s surface—stunningly through clouds, smoke, fog and darkness. SAR stands for Synthetic Aperture Radar. These systems achieve good azimuth resolution that is independent of the slant range to the target, yet use small antennae and relatively long wavelengths to do it.
