Frequency Diverse Array Radar With Logarithmically Increasing Frequency Offset
IEEE Antennas and Wireless Propagation Letters, 2015In recent years, frequency diverse array (FDA) radar with uniform interelement frequency offset has been proposed and investigated. It has been shown that the beampattern of this form of radar is range-angle-dependent, and it exhibits maxima at multiple range values.

Frequency Diverse Array Radar With Time-Dependent Frequency Offset
IEEE Antennas and Wireless Propagation Letters, 2014In recent years, frequency diverse array radar with fixed frequency offset has been proposed and investigated. It has been shown that the beampattern of this category of radar is time-dependent as well as range-angle-dependent. In this letter, we have proposed time-dependent frequency offset to achieve a beampattern that is time-independent for a given

Adaptive Frequency Offset Selection in Frequency Diverse Array Radar
IEEE Antennas and Wireless Propagation Letters, 2014Frequency diverse array (FDA) can provide a range-angle-dependent beam that can be controlled by using a frequency increment between adjacent elements, but the frequency increment is fixed in a basic FDA, which restraints the performance improvement in different environments significantly.

Lamb Wave Frequency Diverse Array
IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control, 2022The 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, 2006This 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.
