Frequency Diversity Array for DOA Estimation
Mehran University Research Journal of Engineering and Technology, 2017 The localization of targets has been presented in this article. DOA (Direction of Arrival) is an important parameter to be determined by radar. The MLE (Maximum Likelihood Estimator) has been widely used to accurately and efficiently estimate the DOAs of multiple targets.

A Joint Frequency Space Design Approach for Efficient Planar Frequency Diverse Arrays
Scientific Reports, 2023 Abstract Antenna arrays benefit from spatial diversity, which enables the control of the pattern specifications in space. Adding frequency diversity to arrays provides an opportunity to control the beams in the Space-Time domain. Contrary to the conventional arrays, the added frequency diversity in the Frequency Diverse Arrays (FDA) leads to ...

Target acquisition and tracking in Frequency Diverse Array radar systems
, 2016 Frequency Diverse Array (FDA) concepts, first introduced in 2006, present a novel approach to electronic beam steering. FDA differs from other conventional arrays in that it applies a small frequency increment to the center frequency for each individual ...

A MISO Frequency Diverse Array Implementation [PDF]
, 2023 The separation of RF signals from different angles of arrival is a key objective for a radarreceiver. A common approach to spatial separation relies on the measurement of a linear phaseprogression across multiple receive antenna elements, where the rate ...

Frequency Diverse Array Super-Resolution Design With Element Locator Polynomial Rooting Approach
IEEE Access, 2023 Unlike traditional phased-array only generating angle-dependent beampattern, the relatively new frequency diverse array (FDA) produces an angle-range-dependent transmit beampattern that can provide many new applications.
