In brief

Abstract

PAGE 1288 Researchers from the College of Automotive Engineering, Seoul, have developed a driver model for use in driver-assisted system technologies. The model is based on a generative adversarial network (GAN) and performs better than a rule-based model when replicating human driving behaviour. PAGE 1265 Chinese researchers present a novel symmetrical antenna design using a chessboard grid hollow substrate (CGHS). Scattering performance of the circularly polarised antenna is enhanced and the device operates between 7 and 20 GHz. Reduction of radar cross section (RCS) at the operating bandwidth is realised by the CGHS. Comparison of different scenarios comparing human, GAN and rule-based behaviour. PAGE 1279 Fei Zhou and colleagues present an anisotropy-based image smoothing method, designed to remove unwanted texture from images. The method was found to compare well with recent similar methodologies. In particular, the methodology presented here did a better job of preserving image edges compared to other methods. Structure of the proposed antenna. PAGE 1303 A collaboration of Chinese researchers presents an AlGaN/GaN ultra-thin barrier hybrid-anode-diode (UTB-HAD) which has been tailored to allow zero-bias microwave detection. Computer simulations found the optimal thickness of the AlGaN barrier to be ∼5 nm. A high-voltage sensitivity of 2.7 mV/μW at zero bias was found.

PAGE 1297 Dr Hidekazu Tsuchida presents a new modulation and detection scheme for frequency modulated continuous wave light detection and ranging (FMCW-LiDAR) systems. The proposed scheme is immune to nonlinear chirp and relative accuracies below ±2 mm/s and ±1 mm for velocity and distance measurements, respectively, are reported.
