The BYU SAR: A Small, Student-Built SAR for UAV Operation [PDF]
2006 IEEE International Symposium on Geoscience and Remote Sensing, 2006 Students at Brigham Young University have developed a new, low-cost synthetic aperture radar (SAR) system, the BYU muSAR. The simple design, based on a linear frequency modulated continuous wave signal (LFM-CW), reduces the size and power compared to a conventional pulsed SAR system.

An Operational Processing Framework for Spaceborne SAR Formations
Remote Sensing, 2023 The paper proposes a flexible and efficient wavenumber domain processing scheme suited for close formations of low earth orbiting (LEO) synthetic aperture radar (SAR) sensors hosted on micro-satellites or CubeSats. Such systems aim to generate a high-resolution image by combining data acquired by each sensor with a low pulse repetition frequency (PRF).
