A microwave sensor for agricultural implements

IEEE International Geoscience and Remote Sensing Symposium, 2003
For soil preparation, the concept of precision agriculture requires real time measurements of soil characteristics and cultivator behavior. The microwave sensor presented in this paper overcomes the limitations of sensors based on optical or ultrasound devices towards agricultural environment (dust, rain, etc.).

Experiments with microwave sensors

International Journal of Remote Sensing, 1992
After an introductory first section, based on the previous history of microwave remote sensing in Europe, a review of achievements is presented in two parts. In the first the material is based on sensor development in the different European countries, whereas in the second non-European sensors are also included.

Microwave‐based sensors

Microwave and Optical Technology Letters, 2015
ABSTRACTA microwave‐based sensor for detection of cracks is proposed. Two types of resonators are designed and analyzed. The first resonator is a ring resonator with stubs attached to the rings. It resonates at a frequency of 2.3 GHz with an insertion loss of −38.51 dB and a return loss of −3.25 dB.

A Microwave Sensor for Steam Quality

IEEE Transactions on Instrumentation and Measurement, 2008
In this paper, a microwave-based in-line sensor for steam quality is described, and test results are reported. The sensor employs a novel high-pressure process seal that minimizes mismatch effects when water condenses on its inner surface.

Microwave vehicle sensor

37th IEEE Vehicular Technology Conference, 1987
A microwave vehicle sensor is described. It is based on microwave radiometry, that is measurement of microwave energy (or temperature) emitted or reflected by bodies. This technique allows detection of passing vehicules as well as measurement of speed and length. Abnormal road surface condition is also detected.

Intercalibration Between Special Sensor Microwave Imager/Sounder and Special Sensor Microwave Imager

IEEE Transactions on Geoscience and Remote Sensing, 2008
The F16 satellite was successfully launched on October 18, 2003, carrying the first special sensor microwave imager/sounder (SSMIS) onboard. In this paper, the SSMIS imaging channels 12-18 are intercalibated against the F15 special sensor microwave/imager (SSM/I) instrument using simultaneous conical overpassing (SCO) observations from both satellites.
