Abstract: Inspired by an effective and computationally efficient approach for detecting and estimating the parameters of a linear frequency modulated waveform incident on an array of receivers, this ...

Abstract: The frequency diverse array (FDA) introduces a frequency offset increment to the transmit signal on adjacent elements, resulting in a unique ‘S’-shaped beampattern. While FDA offers ...

Frequency combs are created by stabilizing the evolution of the carrier–envelope phase of a mode-locked laser. Researchers have now demonstrated a simplified method ...

One art session a week has a similar effect on the ageing process as an extra workout, according to new research ...
