Adaptive radar detection

Electronics Letters, 1985
In the letter a new adaptive procedure for the detection of a radar target in clutter is described. The procedure is based on the development of linear models for the two hypotheses H0 and H1. Under hypothesis H0, there is no target present, and the received signal is modelled as a regressive process.

Radar Target Detection with CNN

2021 29th European Signal Processing Conference (EUSIPCO), 2021
Target detection is a fundamental radar application that is traditionally carried out by Constant False Alarm Rate (CFAR) detectors. This paper proposes a Convolutional Neural Network (CNN) based detector (RadCNN) to replace the standard CFAR detectors for a typical pulsed Doppler radar.

On the feasibility of RADAR detection of high-energy neutrino-induced showers in ice

, 2014
In this article we try to answer the question whether the radar detection technique can be used for the detection of high-energy-neutrino induced particle cascades in ice.

Quantum Illumination at the Microwave Wavelengths [PDF]

, 2015
Quantum illumination is a quantum-optical sensing technique in which an entangled source is exploited to improve the detection of a low-reflectivity object that is immersed in a bright thermal background.

Design and Analysis of Ultra-Thin Broadband Transparent Absorber Based on ITO Film

Micromachines
In this paper, we design an ultra-thin broadband transparent absorber based on indium tin oxide (ITO) film, and we choose polymethyl methacrylate (PMMA) high-transmittance dielectric sheet instead of the traditional dielectric sheet and polyethylene ...
