The amount of the Doppler shift tells us how fast the star is moving relative to us. In addition, the direction of the Doppler shift can tell us the direction of the star's movement. If the spectrum of a star is shifted to the blue end, it is moving toward us; if the spectrum is...

Just days after Sputnik's launch, American scientists noticed that they could pinpoint the satellite's location based on the Doppler shift of its radio signals — a measure of how the wavelengths seemed to stretch out or contract depending on the satellite's movements. This got the researchers ...
• The Array Pattern Synthesis Part III: Deep Learning example shows you how to train a convolutional neural network (CNN) to compute the element weights that produces a given pattern. • The Spectrum Sensing with Deep Learning for Radar and Wireless Communications example shows how to train ...

For this experiment, we selected two games. One is a high-quality graphics game,Gunjack 2: End of Shift, and the second is a low-quality graphics game,Lamper VR;Figure 3shows the visualization of both games using a VR box. These two games were selected from the cloud. ...
The waveform height is described by the maximal power of the returning radar pulse𝜎𝑚𝑎𝑥σmax. It provides information about the backscatter of calm or rough surface conditions. To compute𝜎𝑚𝑎𝑥σmaxfor Envisat as well as SARAL, the maximum waveform power and mission specific re...
