Radar cross section (RCS) sequences, an easy-to-obtain target feature with small data volume, play a significant role in radar classification. However, classification based on RCS sequences has the shortcomings of limited information and low recognition accuracy. In order to overcome RCS-based methods, this paper proposes spatial micro-motion method encoding convolutional neural network (CNN). ...

Realistic high frequency surface wave radar (HFSWR) targets are investigated numerically in terms of electromagnetic wave – target interactions. Radar cross sections (RCS) of these targets are simulated via both the finite-difference time-domain (FDTD) method and the Method of Moments (MoM). The virtual RCS prediction tool that was introduced in previous work is used for these investigations. T...

A method for bandwidth enhancement of radar cross section (RCS) reduction by metasurfaces was studied. Scattering cancellation is one common methods reducing RCS target scatterers. It occurs when the wave scattered scatterer and canceling are same amplitude opposite phase. Since scattering usually narrow, we proposed using metasurfaces, which can control frequency dependence We designed fabrica...

In recent years, microwave wireless power transfer (WPT) has attracted considerable attention due to the increasing demand for various sensors and Internet of Things (IoT) applications. Microwave WPT requires technology that can detect avoid human bodies in transmission path. Using a phantom is essential developing such terms standardization body protection from electromagnetic radiation. this ...

Active Radar Calibrators (ARC), also called calibration transponders, are often used as reference targets for absolute radiometric of radar systems due to their large achievable Cross-Section (RCS). However, before using a transponder target, the hardware itself has be calibrated. A novel method, three-transponder was proposed some years ago and allows RCS digital transponders without any refer...

The performance of a passive radar network can be greatly improved by an optimal radar network structure. Generally, radar network structure optimization consists of two aspects, namely the placement of receivers in suitable places and selection of appropriate illuminators. The present study investigates issues concerning the joint optimization of receiver placement and illuminator selection fo...

Abstract—In this article, a genetic algorithm (GA) is employed to the design of low radar cross section (RCS) patch antennas. Combined with the high frequency simulation software (HFSS) for antenna simulations, the GA performs the optimization of geometric parameters. In order to reduce the RCS while holding the satisfying radiation performance of antennas, the radiation model and scattering mo...
