Frequency Diversity Array for Near-Field Focusing

Electronics, 2020
In this study, a numerical optimization method is proposed to achieve the near-field focusing of square arrays and circular arrays. This method introduced the frequency diversity array (FDA) approach to change the initial amplitude and working frequency.

Lamb Wave Frequency Diverse Array

IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control, 2022
The imaging method based on the conventional phased array (PA) can only realize angle focusing. To break through the above limitations, frequency diverse array (FDA) is first introduced from radar to Lamb wave, which opens up a possibility to realize angle-range focusing in damage localization. The energy pattern of FDA without considering the features

Frequency Diverse Array Radars

2006 IEEE Conference on Radar, 2006
This paper presents a generalized structure for a frequency diverse array radar. In its simplest form, the frequency diverse array applies a linear phase progression across the aperture. This linear phase progression induces an electronic beam scan, as in a conventional phased array.

Realistic Performance Analysis of Frequency-Diverse Arrays Radiation

2023 IEEE 13th International Conference on RFID Technology and Applications (RFID-TA), 2023
In 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 ...
