Computationally Efficient Pruning Before Training Scheme for SNN‐Based Radar Gesture Recognition
In this work, we propose a Spike Timing‐driven Pruning before Training (ST‐PBT) method for radar‐based human gesture recognition. The proposed ST‐PBT performs a single‐shot pruning at the model initialisation, avoiding the expensive computational cost and compression time incurred in the model pre‐training. Furthermore, the ST‐PBT introduces a gradient‐

Precise control of broadband frequency chirps using optoelectronic feedback [PDF]
We demonstrate the generation of wideband frequency sweeps using a semiconductor laser in an optoelectronic feedback loop. The rate and shape of the optical frequency sweep is locked to and determined by the frequency of a reference electronic signal ...

New Design Antenna and Optimization of S‐Band Radar Networks Using CSRR Technology
In this paper, a new design and analysis of a highly compact metamaterial antenna array for radar applications operating in the S‐band (2–4 GHz) is presented. To enhance the electrical and radiation characteristics of the proposed antenna, a slot was introduced into the radiating element, and a novel power divider was employed.
