A Short-Range Range-Angle Dependent Beampattern Synthesis by Frequency Diverse Array
IEEE Access, 2018 In this paper, we propose a new technique to generate a range-angle dependent transmit beampattern by introducing a nonlinear frequency modulation scheme based on arctangent function in the frequency diverse array (FDA) system. The propagation process of

Narrow band space scanning two-dimensional linear frequency diverse array radar
The Journal of Engineering, 2019 Two–dimensional (2D) linear frequency diverse array (FDA) concept is extended to scan a 2D wide angular sector. This is achieved by highly unequal frequency increments in orthogonal 2D directions of the array.

Dynamic Point Transmit Beam Forming of Frequency Diverse Array Radar
工程科学与技术, 2021 Frequency diverse array (FDA) radar applies a small frequency offset between the adjacent elements to synthesize a range-angle-dependent beampattern. It is difficult to control the beam steering for the coupled time-variant beampattern. For this problem,
