Optimal chirp waveforms for long/medium range surveillance radar
, 2015 The optimal design of chirp radar waveforms has to satisfy conflicting requirements in terms of PSLR, compressed pulse width and band occupancy. Optimal solutions for different values of the compression ratio (i.e.

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.Abstract Glacier bed topography is crucial for modeling ice mass loss. However, heavily crevassed regions are challenging to survey using conventional methods, leading to data gaps. We establish a passive seismic approach exploiting naturally occurring crevassing events recorded with a dense seismic array to image the ice–bed interface without spatial ...

The Finite Heisenberg-Weyl Groups in Radar and Communications
EURASIP Journal on Advances in Signal Processing, 2006 We investigate the theory of the finite Heisenberg-Weyl group in relation to the development of adaptive radar and to the construction of spreading sequences and error-correcting codes in communications. We contend that this group can form the basis for

Wearable Kirigami‐Apertured Capacitive Sensors for Continuous Cardiac Volumetric Monitoring
Advanced Functional Materials, Volume 36, Issue 73, 10 September 2026.A wearable kirigami‐apertured carbon nanotube‐paper composite (K‐CPC) capacitive sensor enables cardiac volumetric monitoring. The kirigami process creates a central aperture with cantilevered fibers that confine the electric field, enhancing both sensitivity and lateral resolution.
