(2) Ceilometers were originally conceived to measure cloud-base altitude only, but today, the sensitivity of these instruments is sufficient to provide profiles of backscattered
power from aerosols and clouds.
It means that the ceilometer signal is too noisy and is only capable to measure the signal backscattered
from particles in a low range.
All the above results show that the proposed method in this paper is robust enough regarding the characterization of a 3D rough fractal surface from backscattered

signal from a bottom-moored ADCP based on long-term measurement series," Oceanology, vol.
In our research, the lower values of our AIB parameter, when compared with the literature (20), can perhaps be explained by the effects of cortical bone, which increases the loss of ultrasonic energy by reflection; therefore, less energy was transmitted to the inside of the bone, and, hence, the energy backscattered
from this region was decreased.
Therefore both the particle backscatter and extinction coefficients profiles, at 355 and 532 nm, were obtained by applying the so-called Raman method , which is based on the independent measurements at the laser wavelength as well as at the wavelength of the inelastically backscattered
field computed by FE-BI-MLFMA is denoted as [E.sup.s]([thea],[phi],f).
Compact or hybrid polarimetric SAR has been evolved as a substitute for full-polarimetric SAR in recent times as it offers a reduced complexity, cost, mass and data transmission rate of the SAR system while retaining full-polarimetric information of the target in the backscattered
The method involved treating 90 [micro]m thick plywood sections, which had been cut transversely through the wood-coaling interface using a sliding microtome, with osmium tetroxide (Os[O.sub.4]) prior to examination with a field-emission scanning electron microscope (FE-SEM) operating in backscattered
electron imaging (BEI) mode.
The instruments enable simultaneous observation of up to three different images (secondary electron, backscattered
electron, and digital camera), on-screen measurement, and smart settings for simplified functionality.
Hofstatter and his associates assessed bone mineral density (BMD) distribution using quantitative backscattered
electron imaging, and bone biopsies were collected from nine premenopausal women with idiopathic osteoporosis.
From a typical 1,000-foot altitude, the sensor captures the backscattered
solar radiation and measures the total ethane volume in the column from the aircraft to the ground.
