A two-dimensional Doppler-Radiometer for Earth observation
(IEEE Piscataway, 2000)
Text en actes de congrés
Accés obertCompared to synthetic aperture radars (SARs), the angular resolution of microwave radiometers is quite poor. Traditionally, it has been limited by the physical size of the antenna. However, the angular resolution can be ... -
L-band aperture synthesis radiometry: hardware requirements and system performance
(IEEE Piscataway, 2000)
Text en actes de congrés
Accés obertAperture synthesis radiometry is becoming a feasible concept for imaging applications, especially at low microwave frequencies where it takes clear advantage of the absence of mechanical antenna motion. A 2D interferometric ... -
New radiometers: SMOS-a dual pol L-band 2D aperture synthesis radiometer
(Institute of Electrical and Electronics Engineers (IEEE), 2000)
Text en actes de congrés
Accés obertSince the mid 1980s, aperture synthesis interferometric radiometers have received increased attention to monitor the Earth at low microwave frequencies (L-band), where there is a maximum sensitivity to soil moisture and ... -
Radiometric sensitivity computation in aperture synthesis interferometric radiometry
(Institute of Electrical and Electronics Engineers (IEEE), 1998-03)
Article
Accés obertThis paper is concerned with the radiometric sensitivity computation of an aperture synthesis interferometric radiometer devoted to Earth observation. The impact of system parameters and the use of simultaneous redundant ...
