NASA/JPL Aircraft SAR Workshop Proceedings [PDF]

open access: yes
Speaker-supplied summaries of the talks given at the NASA/JPL Aircraft SAR Workshop on February 4 and 5, 1985, are provided. These talks dealt mostly with composite quadpolarization imagery from a geologic or ecologic prespective. An overview and summary

A Microsatellite Based Synthetic Aperture Radar (SAR).

open access: yes, 2011
Microsatellites are already playing a major role in operational optical-imaging remote sensing applications, viz. the Disaster Monitoring Constellation. However, such satellites are currently limited to providing useful images over cloud free regions during daylight.

Information extraction and transmission techniques for spaceborne synthetic aperture radar images [PDF]

open access: yes
Information extraction and transmission techniques for synthetic aperture radar (SAR) imagery were investigated. Four interrelated problems were addressed. An optimal tonal SAR image classification algorithm was developed and evaluated.

Pipelined digital SAR azimuth correlator using hybrid FFT-transversal filter [PDF]

open access: yes, 1984
A synthetic aperture radar system (SAR) having a range correlator is provided with a hybrid azimuth correlator which utilizes a block-pipe-lined fast Fourier transform (FFT).

A perspective of synthetic aperture radar for remote sensing [PDF]

open access: yes
The characteristics and capabilities of synthetic aperture radar are discussed so as to identify those features particularly unique to SAR. The SAR and Optical images were compared.

Efficient Raw Signal Generation Based on Equivalent Scatterer and Subaperture Processing for SAR with Arbitrary Motion [PDF]

open access: yes, 2014
An efficient SAR raw signal generation method based on equivalent scatterer and subaperture processing is proposed in this paper. It considers the radar’s motion track, which can obtain the precise raw signal for the real SAR. First, the imaging geometry
