DOI: 10.1109/lawp.2018.2867085
Abstract: Unlike a conventional phased array that offers directivity only in the angle domain, a frequency diverse array (FDA) is capable of producing a beampattern that is dependent on both angle and range. In this letter,… read more here.

DOI: 10.1109/lawp.2019.2933547
Abstract: In order to counter passive direction-of-arrival (DOA) reconnaissance for unintended eavesdroppers, this letter proposes the use of frequency diverse array (FDA) to counteract passive DOA reconnaissance using a virtual baseline interferometer. FDA applies a small… read more here.

DOI: 10.1109/tap.2019.2955199
Abstract: Due to the range-angle-dependent beampattern, frequency diverse array (FDA), either in the form of linear array or planar array, has been extensively investigated in recent years. However, the conformal FDA is seldom studied. In this… read more here.

DOI: 10.1109/tvt.2020.3016948
Abstract: A foremost task in frequency diverse array multiple-input multiple-output (FDA-MIMO) radar is to efficiently obtain the target signal in the presence of interferences. In this paper, we employ a novel “low-rank + low-rank + sparse”… read more here.

DOI: 10.1590/2179-10742018v17i31240
Abstract: The basic frequency diverse array (FDA) using linearly increasing frequency increments generates a range-angle dependent beampattern. However, it is coupled in range and angle dimensions and is also periodic in range and time, making its… read more here.
