1. Design and development of a microwave multifrequency polarimetric scatterometer for biosphere remote sensing
Abstract : Microwave radar and radiometer techniques are used to gather crucial information about the earth and its atmosphere. The ERS-1, JERS-1, RadarSAT and NASA’s Mission to Planet Earth projects are designed to study the changing global environment. In all these endeavors, the key instrument is the radar or scatterometer. READ MORE

2. Retrieval of Wind Velocity Vectors Over the Ocean Surface with Spaceborne Synthetic Aperture Radar
Abstract : Wind over the ocean (normally defined at 10 meter height) is one of the main parameters affectingsea state, generating waves and driving currents. Wind field maps with large area coverageand high resolution therefore represent valuable information for a wide range of applications such asinformation for shipping, which carries 80% of the world’s trade, oil platforms and other maritime infrastructures,modeling, analysis and validation of weather models, improving performance of sensorsonboard maritime infrastructures, etc. READ MORE

3. Angle dependent light scattering of functional nanoparticle composites
Abstract : Varies functional nanoparticles play crucial roles in energy- and optical- related applications. The incorporation of functional nanoparticles into non-absorbing polymers to form optical absorption and scattering thin films have attracted considerable interest due to a successful selection of particles and matrices, synergistic effects of separation and fixation of particles, and controllable layer thicknesses and structures.

4. Preparation and optical characterisation of antireflection coatingsand reflector materials for solar energy systems
Abstract : An angle-resolved scatterometer and an integrating sphere for reflectance measurements at oblique angles of incidence have been designed and evaluated. The integrating sphere has a centre-mounted sample holder and the detector sits at the end of the sample holder and therefore always faces the same sphere wall area. READ MORE

5. Retrieval of ocean surface winds and currents using satellite synthetic aperture radar and infrared radiometry
Abstract : This thesis focuses on the development, analysis and evaluation of methods for the retrieval of ocean surface winds with synthetic aperture radar (SAR) and surface currents with infrared (IR) radiometer sensors. The SAR wind speed retrievals are based on geophysical model functions using wind directions obtained with two approaches. READ MORE
