Array Shading to Maximize Deflection Coefficient for Broadband Signal Detection With Conventional Beamforming

IEEE Access, 2021
This paper develops and applies a numerical optimization procedure to compute broadband noise-adaptive weights for delay and sum beamforming that are conditioned to maximize the deflection coefficient at the output of a square law detector for a given ...

Radio environment maps for military cognitive networks: density of small-scale sensor network vs. map quality

EURASIP Journal on Wireless Communications and Networking, 2020
In this paper, we present the dependency between density of a sensor network and map quality in the radio environment map (REM) concept. The architecture of REM supporting military communications systems is described.

Narrow band space scanning two-dimensional linear frequency diverse array radar

The Journal of Engineering, 2019
Two–dimensional (2D) linear frequency diverse array (FDA) concept is extended to scan a 2D wide angular sector. This is achieved by highly unequal frequency increments in orthogonal 2D directions of the array.
