For metal crack nondestructive detection, most conventional sensors are unable to realize the direction detection. In this work, a direction-sensitive microwave sensor is proposed for The consists of rectangular patch resonator and two perpendicular coupled feeding ports, which improves current distribution on surface sensitivity performances verified by simulation measurement experiments. resu...

Satellite microwave and infrared instruments sensitive to upper-tropospheric water vapor (UTWV) are compared using both simulated and observed cloud-cleared brightness temperatures (Tb’s). To filter out cloudy scenes, a cloud detection algorithm is developed for the Special Sensor Microwave/Temperature-2 (SSM/T2 or T2) data using the 92and 150-GHz window channels. An analysis of the effect of c...

This paper describes the architecture of a microwave radar system intended for imaging concealed objects under clothing as a subject walks through the inspection area. The system uses the principle of inverse aperture which is achieved by a person’s movement past a stationary microwave sensor array. In the system, the vertical resolution is achieved by arranging microwave sensors vertically whi...

The Advanced Microwave Scanning Radiometer (AMSR-E) on the Earth Observing System (EOS) Aqua satellite was launched on May 4, 2002. The AMSR-E instrument provides a potentially improved soil moisture sensing capability over previous spaceborne radiometers such as the Scanning Multichannel Microwave Radiometer and Special Sensor Microwave/Imager due to its combination of low frequency and higher...

A microfluidic mixer is integrated with a dual band microwave resonator to allow in situ monitoring of mixing two liquids. The complementary double split ring resonator, which etched the ground plane microstrip transmission line. output channel conducted below near field resonator. Electromagnetic and fluid dynamic simulations has been performed design optimal configuration for this section inc...

1.1 Statement of problem Estimation of soil moisture using microwave remote sensors holds great promise for many applications, including numerical weather prediction and agriculture. However, a scale disparity exists between the resolutions of future satellite-borne microwave remote sensor data (30-60 km) and the much finer scales at which soil moisture estimates are desired (~ 1 km). Hydrology...
