Realistic Performance Analysis of Frequency-Diverse Arrays Radiation
2023 IEEE 13th International Conference on RFID Technology and Applications (RFID-TA), 2023In this work a realistic analysis of the radiation pattern of frequency-diverse arrays is carried out through the introduction of the path loss affecting the field propagation. An essential comparison with the ideal FDA performance is proposed under two scenarios: a basic one with isotropic radiators and absence of coupling between the elements, and a ...

Spatial and directional modulation with random frequency diverse array
2018 IEEE 8th Annual Computing and Communication Workshop and Conference (CCWC), 2018A novel spatial and directional modulation (SDM) method is proposed for enhancing the physical layer security of traditional directional modulation (DM) in the context of random frequency diverse array (RFDA). The novelty of the proposed method is that the concept of spatial modulation (SM) is combined to increase the robustness against the distributed

Comparison of Frequency Diverse Array Patterns with Nonuniform Frequency Offset
2020 IEEE MTT-S International Wireless Symposium (IWS), 2020Frequency Diverse Array (FDA) radar is a new type of radar technology proposed in recent years. It generates a range-dependent beampattern through a small frequency increment among the antenna elements, which overcomes the weakness of phased-array in this respect, so it has many potential applications.

Spatially resolving antenna arrays using frequency diversity
Journal of the Optical Society of America A, 2016Radio imaging devices and synthetic aperture radar typically use either mechanical scanning or phased arrays to illuminate a target with spatially varying radiation patterns. Mechanical scanning is unsuitable for many high-speed imaging applications, and phased arrays contain many active components and are technologically and cost prohibitive at ...

Cognitive frequency offset calculation for frequency diverse array radar
2015 12th International Bhurban Conference on Applied Sciences and Technology (IBCAST), 2015Frequency diverse array (FDA) radars have the ability to generate a beam pattern that is a function of range angle and time. The wavy beam pattern can be controlled by using a suitable frequency increment applied at the input of the array elements. Instead of using fixed frequency increment for FDA, we propose a cognitive frequency offset calculation ...

Frequency Diverse Array Information Geometry Analysis
2020 14th European Conference on Antennas and Propagation (EuCAP), 2020Different classic phased-array that generates only angle-dependent transmit beampattern, frequency diverse array (FDA) offers both angle-dependent and range-dependent transmit beampattern. This paper adopts the information geometry theory to study the fundamental information resolution for a general FDA radar system.

Adaptive and diversity arrays for frequency-hopping systems
MILCOM 1999. IEEE Military Communications. Conference Proceedings (Cat. No.99CH36341), 2003The performance of an adaptive array is compared with that of an ideal diversity array for frequency-hopping systems in a mobile peer-to-peer communication network. Both independent and completely correlated Rayleigh fading at the antennas are examined.

Electronic scanning is the most desirable feature of state-of-the-art radar systems. With electronic scanning, it is possible to steer the main beam of an array antenna instantaneously into a desired direction where no mechanical mechanism is involved in the scanning process.
