Radar Position Estimation by Sequential Irradiation of ESM Receivers

open access: yesSensors, 2021
In this article, a new technique for determination of 2D signal source (target) position is proposed. This novel approach, called the Inscribed Angle (InA), is based on measuring the time difference of sequential irradiation by the main beam of the ...

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

open access: yesThe 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.
