How is the Vehicle's Speed Detected by the Radar? Radar makes use of electromagnetic waves to detect objects and give info (speed, distance, etc) about them. It makes use of Doppler Effect to determine the vehicle's speed. They calculate and scale the variation of frequency between the received and sent radio waves (echo). The frequency will be lower if the object is moving away and is higher i...

in this paper, a new propagation model based on utd for multiple diffraction paths in cellular mobile radio communications in urban environments is proposed. moreover, the most rigorous novel utd-based expressions for multiple diffractions by buildings and excess path losses are d - rived and analyzed. for this purpose, building rows are supposed to have rectangular cross-sections with the same...

Proof of principle object composition identification based on inductive measurements with an atomic magnetometer has been demonstrated in highly engineered laboratory conditions. Progress the development portable miniaturised magnetometers encouraged parallel measurement technologies involving this sensor, particular concepts that would enable operation complex test scenarios. Here, we explore ...

The topical issue today is the study of pragmastylistics Kazakh radio. Despite fact that history radio has been studied well enough, pragmatics and stylistics programs did not become object research. Another reason for relevance pragmatic broadcasts recently journalism departed from classical canons. Genres are being transformed, broadcasts, news reports losing, an increase in thematic musical ...

The steep spectrum of IRAS F02044+0957 was obtained with the RATAN-600 radio telescope at four frequencies. Optical spectroscopy of the system components, was carried out with the 2.1m telescope of the Guillermo Haro Observatory. Observational data allow us to conclude that this object is a pair of interacting galaxies, a LINER and a HII galaxy, at z = 0.093. Trushkin & Verkhodanov (1995) compi...
