Orbit maintenance and characteristics for a SAR satellite
AIAA/AAS Astrodynamics Specialist Conference and Exhibit, 1998A newly proposed Synthetic Aperture Radar (SAR) Earth-imaging mission, LightSAR, requires the orbit to be maintained within a 125-meter radius tube centered on a reference orbit over the lifetime of the satellite. Reference orbits were defined around 81° inclination with ground track closure of about 1 meter, and the radial closure of about 17 meters ...

Satellite SAR Geocoding For Earth Mapping
SPIE Proceedings, 1989The forthcoming scenario of remote sensing satellites is characterised by a growing utilization of Synthetic Aperture Radar (SAR) sensors. Among these sensors, the NASA SIR-C (in combination with German/Italian X-SAR), the Canadian Radarsat, the Japanese JERS-1 and the European ERS-1 will produce high resolution, day and night, cloud penetrating images

We created a prototype for a flexible last multithreaded high precision PC satellite SAR processor, which can operate on a network of low cost PC platforms. The network approach provides a scalable solution to divide the workload over multiple computers, thereby reducing the computation time.

A new SAR sensor designed for micro-satellites
2010 IEEE International Geoscience and Remote Sensing Symposium, 2010Micro Satellites (μSATs) are good opportunities for small countries. This paper describes a new design of a SAR for a μSAT. The centre frequency and the SAR processing were optimized in a way to allow the realization of a simple but capable system that provides many interesting opportunities for researchers and allows participating to international ...

Evolution of Ship Detectors for Satellite SAR Imagery
1999A two-stage evolution scheme is proposed to obtain an object-detector for an image analysis task, and is applied to the problem of ship detection by inspection of the SAR images taken by satellites. The scheme: (1) affords practical evolution times, (2) is structured to discover fast automatic detectors, (3) can produce small detectors that shed light ...

A cooperation earth observation model of SAR satellite and optical remote sensing satellite
2014 IEEE Geoscience and Remote Sensing Symposium, 2014A cooperation earth observation model constituted by two SAR satellites and one optical remote sensing satellite is proposed. In this model, the optical remote sensing satellite orbit plane locates in the middle of two SAR satellites, and two SAR satellites observe the same ground area from two sides of the optical satellite respectively.

An On-Orbit Ship Detection and Classification Algorithm for Sar Satellite
IGARSS 2019 - 2019 IEEE International Geoscience and Remote Sensing Symposium, 2019Ship detection using synthetic aperture radar (SAR) plays a vital role in the wide area ocean surveillance. Especially the real-time ship detection and classification, significantly promotes the illegally operating ships monitoring performance. In this study, an on-orbit ship detection and classification method is developed for SAR satellite.
