In this paper, we propose a method for efficient target classification based on the spatial features of the point cloud generated by using a high-resolution radar sensor. The frequency-modulated continuous wave radar sensor can estimate the distance

With the emergence of advanced communication technologies such as infrastructure-free communication networks, the need for proactive eavesdropping which can constantly monitor and intervene in the communication network is growing. In response to thos

In this paper, we propose a method for detecting the misalignment of automotive radar sensors. Ensuring the accurate operation of automotive radar sensors is essential for the safety of drivers and passengers. However, when radar sensors are misalign

In this paper, we present a deep neural network aimed at enhancing the resolution of range-Doppler (RD) maps in frequency-modulated continuous wave radar systems. The proposed deep neural network consists of an U-net-based generator and a discriminat

In a binary phase shift keying (BPSK)-based multiple-input and multiple-output (MIMO) frequency-modulated continuous wave (FMCW) radar system, real and ghost targets are detected simultaneously, causing ambiguity in target detection. In this paper, w

Abstract The number of antennas in automotive frequency‐modulated continuous wave (FMCW) multiple‐input multiple‐output (MIMO) radar systems is increasing. Existing greedy or subspace‐based methods cannot quickly and accurately estimate the d

Abstract In this study, a target classification method based on point cloud data in a high‐resolution radar sensor is proposed. By using multiple antenna elements arranged in horizontal and vertical directions, pedestrians, cyclists and vehicles ca

In this paper, we propose a method for extracting the structure of an indoor environment using radar. When using the radar in an indoor environment, ghost targets are observed through the multipath propagation of radio waves. The presence of these gh

Abstract Concentration of drivers on traffic is a vital safety issue; thus, monitoring a driver being on road becomes an essential requirement. The key purpose of supervision is to detect abnormal behaviours of the driver and promptly send warnings t

Radar signals generated from other vehicles can act as interference to ego-vehicle, which degrades the inherent detection performance of radar. In this paper, we address an efficient solution to the interference problem in frequency-modulated continu
