Analysis of Radar Cross Section of a Battleship Equipped with an Integrated Mast Module Based on PO and PTD

Abstract

In this paper, we analyze the radar cross section (RCS) of a battleship equipped with an integrated mast module (IMM). The RCS of a battleship equipped with an IMM is calculated based on physical optics (PO) and the physical theory of diffraction (PTD), and is analyzed in terms of the mast shape, incident angles, and polarization.

Shape Optimization of an Integrated Mast for RCS Reduction of a Stealth Naval Vessel

“…After that, the RCS of an initial model of the integrated mast is calculated and analyzed. In order to evaluate the RCS of the integrated mast, the RCS pattern and the representative RCS values such as the geometric mean and the arithmetic mean [3,4,21,22] are used. The geometric mean and the arithmetic mean are given as follows, respectively.…”

“…As the shape of the integrated mast is one of the most important factors and must be considered in the early stages of the concept/design, it is necessary to know in advance the characteristics of the RCS of the integrated mast and the naval vessel equipped with the integrated mast. To investigate the RCS characteristics of naval vessels, there have been many studies [13,[18][19][20][21][22]. The RCS of naval vessels has been investigated [18,19] and its properties have been analyzed according to the side slope of the superstructure [13] and exterior equipment arrangement such as the sensor and radar [20].…”

“…However, related studies on the RCS of the integrated mast itself seem to be lacking. Although the previous studies were conducted to analyze the RCS of the integrated mast [21] and the simplified battleship equipped with the integrated mast [22] an investigation on the optimization of the integrated mast shape for RCS reduction has not been presented. Therefore, it is of great significance to optimize the mast shape for RCS reduction and to analyze the RCS of the naval ship equipped with the optimized mast.…”

Indoor exclusion zone analysis in a nuclear power plant with wirelessHART application

“…Fig. 3 shows the indoor geometry descriptions using Wireless InSite commercial electromagnetic (EM) simulation software [24], which is useful when indoor propagation characteristics are investigated by a ray-tracing method [25,26]. The simulation tool is particularly well suited for fast simulation analysis of large indoor spaces.…”

Drop Algorithm for Super Resolution Scattering Center Extraction

“…The radar cross section (RCS) is the ratio of the scattered power to the incident power in the farfield [1]. The RCS provides a great deal of information about a target [2].…”
