Pulse compression is an important technology in modern radar system, which promotes the developments of modern radar technologies towards higher speed and ranging accuracy. The FMCW signals, with the ...

While the concept of time travel has long captured public imagination, modern physics actually approaches time in a much more ...

Synthetic-aperture radar, in which a moving radar is used to simulate a very large antenna and obtain high-resolution images, is typically not the stuff of hobbyists. Nobody told that to [Henrik ...

Most often ultrasonic transducers are used for distance measurements, and in the DIY world, usually as a way for robots to detect obstacles. But for a weekend project, [Vinod.S] took the ultrasonic ...

A 10-MHz sinusoidal carrier wave of amplitude 10 mV is modulated by a 5-kHz sinusoidal audio signal wave of amplitude 6 mV. Find (a) the frequency components of the resultant modulated wave and (b) ...

Special Issue No. 56. Proceedings of the 10th International Coastal Symposium ICS 2009, Vol. II (2009), pp. 913-917 (5 pages) Published By: Coastal Education & Research Foundation, Inc. This study ...

So just how does the modulating of radio waves enable data transmission? The answer is found in the concept of coding. Coding refers to a modulation pattern that is understood and shared by both a ...

Signal reliability is paramount in many wireless applications. For example, crane controls or other critical control equipment must not lose connection as the equipment moves. Stage actors must ...
