Interferometric synthetic aperture radar (InSAR) is a rapidly evolving technology for DTM generation. It exploits the coherent nature of SAR imaging to measure stereo parallaxes in the mm and cm regime from phase differences. InSAR systems are active microwave sensors; they operate independent of cloud cover and sun illumination. This paper reviews the basic principle and the properties of spac...

Active integrated antennas (AIA’s) provide a new paradigm for designing modern microwave and millimeter-wave architecture with desirable features such as compactness, light weight, low cost, low profile, minimum power consumption, and multiple functionality. This paper reviews recent research and development related to this emerging technology with emphasis on its applications in high-efficienc...

The goal of this work is to intercompare four global land surface emissivity products over various landcover conditions to assess their consistency. The intercompared land emissivity products were generated over a 5year period (2003–2007) using observations from the Advanced Microwave Scanning Radiometer – Earth Observing System (AMSR-E), the Special Sensor Microwave Imager (SSM/I), the Tropica...

This paper deals with passive microwave imaging for fire detection by means of a single-channel ground-based radiometer. The simulation of images sensed in the presence of fire spots under different environmental and operative conditions will be presented. We will refer to a low-cost ground-based radiometer operating at 12.65GHz. Scenarios where fires are un-visible and IR sensors are not usefu...

In this research we examine active and passive microwave to snow water equivalent (SWE) and to investigate the potential of combining active and passive microwaves to improve the estimation of SWE. The study area is located in Great Lakes area between the latitudes of 41N–49N and the longitudes of 87W–98W. Passive microwave are obtained from DMSP SSM/I sensors provided by NSIDC. Active microwav...

In this paper we review recent design methodologies for fully dielectric electro-optic sensors that have applications in non-destructive evaluation (NDE) of devices and materials that radiate, guide, or otherwise may be impacted by microwave fields. In many practical NDE situations, fiber-coupled-sensor configurations are preferred due to their advantages over free-space bulk sensors in terms o...

EXTENDED ABSTRACT Soil moisture plays a vital role in the atmosphere-land interactions, hydrological simulation, weather numerical prediction and agricultural arid monitoring. It may control the partition of water and energy into sensible heat flux, latent heat flux, evapotranspiration, runoff and baseflow between land and atmosphere respectively. In order to obtain the profile of soil moisture...

This paper is concerned with robotic applications using a ground‐based radar sensor for simultaneous localization and mapping problems. In mobile robotics, radar technology is interesting because of its long range and the robustness of radar waves to atmospheric conditions, making these sensors well‐suited for extended outdoor robotic applications. Two locali...

he long-term goal of the research effort discussed in this article is to determine the feasibility of obtaining quantitative information about the near-surface wind field and perhaps other parameters that characterize the marine atmospheric boundary layer from an analysis of synthetic aperture radar (SAR) imagery. Because of its potential for yielding such information at high spatial resolution...

A cloud detection algorithm based on ground-based remote sensors has been developed that can differentiate among various atmospheric targets such as ice and water clouds, virga, precipitation, and aerosol layers. Standard cloud type and macrophysical properties are identified by combining polarization lidar, millimeter-wave radar, infrared radiometer, and dual-channel microwave radiometer measu...
