Sentence examples for reflected by objects from inspiring English sources

It is a form of "passive" radar, which goes back a long time.Although it had been known since the late 19th century that radio waves can be reflected by objects, it was not until the years leading up to the second world war that a number of countries began secretly developing ways to detect aircraft.

Thermal imaging refers to the process of capturing the long-wave IR radiation emitted or reflected by objects in the scene, which is undetectable to the human eye, and transforming it into a colored or grayscale image.

This method uses the Doppler shift (i.e. the frequency change that light undergoes when reflected by objects in motion, such as RBCs) and has been proposed to be a valid method for the monitoring of microcirculatory function in small, discrete tissue areas (for a review see Smits et al, 1986).

Polarimetric synthetic aperture radar (PolSAR) is an active microwave remote sensing imaging radar, which emits electromagnetic pulses with different polarimetric states and then receives echoes reflected by ground objects, so as to obtain the scattering characteristics of the ground object target objects.

Image enhancement techniques aim to amplify the light reflected by the objects in the monitored scene to improve visibility.

Light is neither absorbed nor reflected by the objects, passing "like water flowing around a rock," according to the researchers.

This method relies on the Doppler shift, assessing the frequency change undergone by light when reflected by moving objects, such as RBCs, and is a valid technique for measurement of microcirculatory function in small tissue areas (Smits et al, 1986).

Morgans and Ord [ 28] provide a detailed discussion of the assumptions of this type of colour analysis in relation to the range of light wavelengths reflected by natural objects and how colour might be viewed by different types of animals (see also [ 65]).

Taking into account its permittivity, permeability and conductivity as well as the typical frequency band employed by a UWB sensor, a person reflects and absorbs the energy of electromagnetic waves emitted by the sensor transmitting antenna or reflected by another object or target [49].

The light reflected by an object depends both on the object's surface reflectance characteristics and on the composition of the light illuminating the object.

As a result of using translucent layer 64b under the display surface to diffuse the IR light passing through the display surface, as an object approaches the top of display surface 64a, the amount of IR light that is reflected by the object increases to a maximum level that is achieved when the object is actually in contact with the display surface.
