An inflatable L-band microstrip SAR array

IEEE Antennas and Propagation Society International Symposium. 1998 Digest. Antennas: Gateways to the Global Network. Held in conjunction with: USNC/URSI National Radio Science Meeting (Cat. No.98CH36194), 2002
Inflatable structures have been identified as one of the enabling technologies to achieve low mass, high packaging efficiency, and reliable deployment for future NASA spaceborne synthetic aperture radar (SAR) array antennas. A current L-band SAR antenna development, with an aperture size of 10 m/spl times/3 m, is required to have the capabilities of ...

Using L-band SAR images to map coastal wetlands

2012 IEEE International Geoscience and Remote Sensing Symposium, 2012
The National Wetland Inventory (NWI) in the USA is required, by congress mandate, to map wetlands every ten years. The last time the wetlands were map was in the mid-1980s using labour intensive, aerial photograph analysis techniques. The goal of this project is to map wetlands, based on the US-FWS NWI coastal wetland classes, in North Carolina using ...

Motion compensation of L-band SAR using GNSS-INS

2017 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2017
An experiment using the Vector Network Analyzer, modified from LiSALAB Ground-Based Synthetic Aperture Radar (GBSAR) system has been performed to evaluate the feasibility of constructing a mobile SAR system operating at L-band. Data was collected in a parking lot in Purdue University, West Lafayette.

Assessing L-band SAR modes for commercial forest management

IGARSS 2003. 2003 IEEE International Geoscience and Remote Sensing Symposium. Proceedings (IEEE Cat. No.03CH37477), 2004
The use of remote sensing in UK forestry has previously been limited to Interpretation of aerial photographs. One new technique which is near commercial realisation is Synthetic Aperture Radar (SAR). Various approaches to using SAR data exist. This paper demonstrates the use of dual-baseline coherence to classify a forested landscape to improve upon a ...

Faraday rotation effects on l-band spaceborne sar data

IEEE Transactions on Geoscience and Remote Sensing, 2003
Several proposed near-future spaceborne radar missions, such as the Advanced Land Observing Satellite (ALOS) and TerraSAR, will include an L-band instrument. At such low frequencies, the Faraday rotation in the ionosphere, which rotates the polarization plane of the radar signal, becomes an important consideration in instrument design.

A wide swath, full polarimetric, L band spaceborne SAR

2008 IEEE Radar Conference, 2008
The design of a space-borne synthetic aperture radar (SAR) with large swath coverage in full polarimetric mode is a challenging task in L band. The requirement for full-polarimetry involves a doubling of the PRF, reducing the available swath and making range ambiguities a serious problem, particularly for the cross polarization. This is the case of the

Development and Experiment of L-Band Sar for Ranging and Imaging Target

IGARSS 2018 - 2018 IEEE International Geoscience and Remote Sensing Symposium, 2018
A synthetic aperture radar (SAR) is globally studied in various purposes. Especially, the SAR applications such as image processing and image application have been dealt with several papers. However, it is hard to approach for student researcher a development of the SAR system. In this paper, we design and develop an L-band SAR system which has a small

MAPSAR: a small L-band SAR mission for land observation

Acta Astronautica, 2005
Abstract This paper introduces Multi-Application Purpose SAR (MAPSAR). A new Synthetic Aperture Radar (SAR) mission for earth observation. MAPSAR is the result of a joint pre-phase A study conducted by INPE and DLR targeting a mission for assessment, management and monitoring of natural resources.

Rice paddy monitoring by L-band MIMP SAR approach

2017 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2017
SAR remote sensing has been expected as an efficient rice crop monitoring tool due to its flexible operability with wide swath. Though many researchers have intensively analysed the backscatter, there still exist non-negligible mysteries to extract physical parameters.

First Results from the Ingara L-Band SAR

2018 International Conference on Radar (RADAR), 2018
A significant challenge for Intelligence, Surveillance and Reconnaissance (ISR) systems is the detection and possible identification of concealed targets, for example vehicles and structures under foliage. Low Frequency (LF) imaging radar sensing offers a number of unique phenomenologies and modalities that can address this problem.
