Abstract Due to the controllable degrees of freedom of frequency diverse array in the distance dimension, the frequency diverse multiple‐input multiple‐output (FDA‐MIMO) radar can easily deal with mainlobe interference, which is often difficult

Abstract The range‐angle coupling characteristics of traditional frequency diverse array (FDA) will deteriorate target localization performance. To address this problem, several decoupling methods for FDA have been developed in the past decade, mai

Abstract By controlling the null distribution in the range‐angle dimension, the frequency diverse array (FDA) can handle range‐dependent interference, which is usually difficult to solve for the traditional phased array. However, the current inve

For metal crack nondestructive detection, most conventional crack sensors are unable to realize the crack direction detection. In this work, a direction-sensitive microwave sensor is proposed for metal crack detection. The proposed sensor consists of

Due to the introduction of frequency offsets, the pattern synthesis problem of sparse Frequency diverse array (FDA) becomes more complicated than that of the phased array. A typical way to solve this problem is to use a global optimization algorithm,

The single-pixel imaging (SPI) technique enables the tracking of moving targets at a high frame rate. However, when extended to the problem of multi-target tracking, there is no effective solution using SPI yet. Thus, a multi-target tracking method u

The chirp sequence waveform is one of the most commonly used waveforms for automotive frequency‐modulated continuous wave radars. When a chirp sequence waveform is applied, the range–Doppler processing method based on two‐dimensional fast Fouri
