Remote Radar Sensing: Atmospheric Structure and Insects

Science, 1973
A high-resolution radar sounder has been used in the simultaneous detection of atmospheric structure and insects. The vertical distribution of insects was often correlated with atmospheric structure. Continuous recordings revealed diurnal fluctuations and layering of insects at various altitudes.

Radar Remote Sensing in Biology

BioScience, 1967
Radar's potential as a sensor for surveys of natural and cultivated vegetation has recently been demonstrated in a preliminary way. Its combination of fine resolution from long distances with a virtual independence of weather and time of day makes radar particularly attractive for wide area surveys that must be performed quickly.

Advance MMICs for remote sensing and radar applications

33rd European Microwave Conference Proceedings (IEEE Cat. No.03EX723C), 2003
Modern remote sensing systems and radars are more and more based on electronically steered antennas. Instead of using one high power tube, each radiating element must contain a full T/R module allowing an individual modulation of amplitude and phase of both transmit and receive signal.

Radar and optical modelling of forest remote sensing

2012 IEEE International Geoscience and Remote Sensing Symposium, 2012
This paper describes a parallel model which goal is to carry out sensibility studies on simulated radar and optical remote sensing forest data. It presents how the model has been set up, with a forest growth model as an input of an optical hyperspectral model and a Synthetic Aperture Radar (SAR) model.

Classification of radar images in polarimetric remote sensing

Proceedings 1998 International Conference on Image Processing. ICIP98 (Cat. No.98CB36269), 2002
This paper describes the use of polarimetric data for Earth terrain classification. The Cloude (1992) target decomposition theorem is applied to classify the scene into several classes having each one a distinct physical interpretation. The implemented algorithm, under its new version, uses two parameters, not often exploited in radar remote sensing ...

Wideband imaging radar for cryospheric remote sensing

2014 IEEE Geoscience and Remote Sensing Symposium, 2014
A wideband multi-channel airborne sounding and imaging radar for cryospheric remote sensing applications has been recently developed by the Center for Remote Sensing of Ice Sheets (CReSIS). The radar is designed to measure ice thickness, image the ice-bed interface, and map internal layers in ice sheets and glaciers. This newly-developed radar uses the

Remote sensing of the atmosphere by VHF radar experiments

Naturwissenschaften, 1978
Problems in atmospheric dynamics, in particular in micro- and mesoscale processes, which can be solved by radar investigations, are summarized. The method of atmospheric radar experiments is described. Some relevant results obtained with the new SOUSY-VHF-Radar are presented, including observations of a warm-front passage, of layered structures, and of

Radar remote sensing

1999
The scattering behaviour of the earth's surface at radar wavelengths can provide useful information about many natural processes. Since most applications of remote sensing require large areas to be surveyed, HF radars provide the only useful ground-based systems. These are used for sea sensing. Extensive coverage can be provided by air-borne platforms.

Remote Sensing with imaging radar: a review

Geoforum, 1970
Abstract Research during the past five years has enabled us to define certain potentials and problems in the use of radar imaging systems for mapping and resource evaluation. This review article concentrates on the applications and difficulties encountered with a multiple polarization K-band real aperture radar system and touches very briefly on ...

Radar Remote Sensing and Offshore Technology

Offshore Technology Conference, 1980
ABSTRACT It has been nearly two years since SEASAT, the first satellite dedicated to Oceanography, was launched. During its one hundred days, SEASAT's Imaging Radar penetrated clouds and foul weather operating day and night, mapping pertinent areas of the globe with better than 25m ground resolution.
