Exploring combinations of multi-temporal and multi-frequency radar backscatter observations to estimate above-ground biomass of tropical forest
Above-ground biomass Tropical forest Synthetic Aperture Radar Multi-frequency Multi-temporal
2024/2/5
Approaches exploiting the complementary information on forest above-ground biomass (AGB) contained in multi-temporal and multi-frequency radar backscatter have hardly been explored in the tropics. Hav...
THEORETICAL MODELLING STUDY ON THE RELATIONSHIP BETWEEN MULTI-FREQUENCY MICROWAVE VEGETATION INDEX AND VEGETATION PROPERTIES (OPTICAL DEPTH AND SINGLE SCATTERING ALBEDO)
Microwave Vegetation Index Matrix Doubling Model Optical Depth Single Scattering Albedo Soil Moisture Roughness
2018/5/15
This paper presents a theoretical study of derivation Microwave Vegetation Indices (MVIs) in different pairs of frequencies using two methods. In the first method calculating MVI in different frequenc...
Estimating Forest Biomass in Temperate Forests Using Airborne Multi-frequency Polarimetric SAR Data
Synthetic Aperture Radar (SAR) Polarimetry Multi-frequency
2015/8/28
We used multi-sensor, multi-frequency and multi-polarization SAR data for biophysical parameter retrieval in plantation forests of
Northern Japan. The statistical relationships with different biophys...

Multi-frequency emission analysis and constraining redshift of 3C 66A
BL Lacertae objects individual galaxies active gamma rays general
2010/11/11
The emission mechanism of TeV blazar 3C 66A is studied by employing the multi-wavelength
observational data. The GeV spectrum observed by Fermi-LAT can’t be explained by pure synchrotron self-Compton...

2009/3/12
We test the prediction of Hamilton and Helfand (1993) that faint
radio selected galaxies are a new class contributing to the diffuse X-ray background
(XRB) radiation. The test is based on the correl...
Experimental Demonstration of Phase-Matched OCDM Using PLC-LN Multi-Frequency Self-Homodyne Module
OCDM PLC-LN Multi-Frequency Self-Homodyne Module
2015/8/6
We propose and demonstrate phase-matched OCDM transmission based on multi-frequency self-homodyne detection. The feasibility is verified based on experiments using a developed PLC-LN module at the bit...
Application of dynamic vibration absorbers in structural vibration control under multi-frequency harmonic excitations
Dynamic vibration absorber State-switched absorber Multi-frequency Frequency-tuning
2015/3/30
In this research, the response properties of a single-degree-of-freedom system under dual harmonic excitation are analyzed to provide some principles for the choice of time span and step in the simula...
