Advances on Frequency Diverse Array Radar and Its Applications
Leida xuebao, 2018 Unlike the conventional phased array that provides only angle-dependent transmit beampattern, Frequency Diverse Array (FDA) employs a small frequency increment across its array elements to produce automatic beam scanning without requiring phase shifters ...

Analysis of beampattern dwell time for planar frequency diverse array
IET Signal Processing, 2021 Frequency diverse array (FDA) has received much attention due to its both range–angle‐dependent beampattern. However, most of the existing works focus on the linear FDA, and time‐varying characteristics of its beampattern only give a rough qualitative ...

Frequency Diverse Array Radar Cramér-Rao Lower Bounds for Estimating Direction, Range, and Velocity [PDF]
International Journal of Antennas and Propagation, 2014 Different from phased-array radar, frequency diverse array (FDA) radar offers range-dependent beampattern and thus provides new application potentials. But there is a fundamental question: what estimation performance can achieve for an FDA radar? In this

Numerical Model of a 28-GHz Frequency Diverse Array Antenna
Proceedings, 2020 In this work we make use of the frequency diverse array (FDA) concept, whose design is based upon a frequency increment across the antenna elements to generate a beam steering that is a function of angle, time and range.

Antenna Element Index Modulation for Frequency Diverse Array
International Journal of Antennas and Propagation, 2019 In this paper, we propose a new architecture and provide performance analysis for frequency diverse array (FDA) Radar combined with the index modulation (IM) techniques. Here, the IM concept is applied upon frequency offsets in an FDA.

Prospects of FMCW-based frequency diverse array radar [PDF]
The Journal of Engineering, 2019 The linear frequency modulated (LFM) frequency modulated continuous wave (FMCW)-based frequency diverse array (FDA) radar concept is investigated in detail. The radar operates as a linear pulsed FMCW/FDA in the transmission (TX) mode while it operates as

Space scanning FMCW-based two-dimensional frequency diverse array radar [PDF]
The Journal of Engineering, 2019 The frequency-modulated continuous wave (FMCW)-based frequency diverse array (FDA) radar concept is extended to two dimensions (2D). The radar operates as a linear pulsed FMCW/FDA in the transmission (TX) mode while it operates as a pulsed FMCW/phased ...

Frequency Diverse Array Radar Signal Processing via Space-Range-Doppler Focus (SRDF) Method
Leida xuebao, 2018 To meet the urgent demand of low-observable moving target detection in complex environments, a novel method of Frequency Diverse Array (FDA) radar signal processing method based on Space-Rang-Doppler Focusing (SRDF) is proposed in this paper. The current
