We demonstrate, against current knowledge, that Anderson localization can occur for wavepackets outside the spectral extent of the disordered potential, mediated by second order transitions.
Cognitive radar (CR) has recently been considered as a natural next step for traditional radar. The cognitive property assumes both transmitter and receiver to be able to dynamically adapt to environment changes. In this work, we propose to exploit sub-Nyquist sampling methods that have been originally proposed to reduce the sampling rate bottleneck at the receiver. For CR, we extend this approach...
Pulse Doppler radars measure both the targets distance to the transceiver and their radial velocity, through the estimation of the time delays and Doppler frequencies, respectively. This digital processing is traditionally performed on samples of the received signal at its Nyquist rate, which can be prohibitively high. Overcoming the rate bottleneck, sub-Nyquist sampling methods have been proposed...
