Radio waves are electromagnetic waves whose wavelength is more than the infrared rays. Therefore, the frequency of the radio waves is less than that of the infra-red rays. Wave Travel: The wavelength of a wave, {eq}\lambda {/eq} (m), is the distance...
Bolometer sensors are good candidates for room-temperature THz imaging thanks to their maturity and capability to sense THz waves on the whole spectrum. St... DT Nguyen,F Simoens,JL Ouvrier-Buffet,... - International Conference on Microwave Radar & Wireless Communications 被引量: 34发表: 2012...
Strong attenuation of millimeter wave due to precipitation particles is the most serious problem when we use K-band (0.86cm wavelength) radar for the observation of the precipitation. In this paper, we calculated the attenuation of K-, X- (3.2cm) and C-band (5.6cm) waves based on a mode...

The scattering of electromagnetic waves by small obstacles has been measured in several cases which are of interest in connection with the interpretation of radar echoes from rain and cloud formations. The measurements were made at a frequency of 3000 Mc/sec by an impedance‐bridge technique, the...
(In dry, sandy soils, GHz radar waves can propagate tens of meters.) A more useful central frequency for GPR to detect buried utilities is 250 MHz, which can penetrate 3 m or more in many soils and provide a resolution of about 10 cm in soil with an index of refraction of 3. Two ...
Greetings, Please imagine a huge pile of rubble, meters deep. Somewhere inside, there's a device emitting a certain signal. This signal can be picked up by a radar-like device which locates the origin of that signal, with the least interference from the pile of rubble, concrete blocks, me...
