In this paper, a novel design method that integrates broadband agile radiation and controllable scattering performance in one surface is proposed for an active metasurface. Each unit cell of the metasurface is incorporated with tunable devices, such as an electronic or micro-electro-mechanical-system MEMS varactor, to obtain frequency or spatial electromagnetic EM wave modulation.

Sneha, Hema Singh, R. The estimation of RCS of a phased array depends on various parameters, namely, array geometry, operational frequency, feed network, mutual coupling between the antenna elements and so fourth. This paper presents the estimation of RCS of linear dipole array with series-feed network by tracing the signal path from the antenna aperture into the feed network. The effect of mutual coupling exhibited by the dipole antenna is considered for three configurations namely, side by side, collinear, and parallel in echelon. It is shown that the mutual coupling affects the antenna pattern and hence RCS significantly for larger scan angles. Further it is inferred that the RCS of phased array can be optimized by i reducing the length of the dipole, ii termination of the isolation port of the coupler with a suitable load, and iii using suitable amplitude distribution.

Use of this web site signifies your agreement to the terms and conditions. The term "radar cross section" is defined, and the characteristics of different types of test ranges are given. The responsibilities of the test range operators are shown to involve test and calibration of the measurement range systems as well as accurately carrying out the measurements. Techniques are described for each stage of this process. Scope: This recommended practice establishes processes for the measurement of the electromagnetic scattering from objects.

Radar cross section prediction and reduction for naval ships

Radar cross-section of complex target like vehicles, trees, human beings, buildings are rather impala pe. A stationary target produces no signal, no matter how close it is or what its radar cross-section is like. Much like the Tyrannosaurus that eats Gennaro in Jurassic Park, it can only "see" movement.

A 100,000 Scale Factor Radar Range

Radar cross-section RCS is a measure of how detectable an object is by radar. Therefore, it is called electromagnetic signature of the object. A larger RCS indicates that an object is more easily detected. An object reflects a limited amount of radar energy back to the source. The factors that influence this include: [1].

The radar cross section of an object is an important electromagnetic property that is often measured in anechoic chambers.

Radar cross section RCS is the measurement of the reflective strength of a target. Reducing the RCS of a naval ship enables its late detection, which is useful for capitalizing on elements of surprise and initiative. Thus, the RCS of a naval ship has become a very important design factor for achieving surprise, initiative, and survivability. The purpose of this paper is to provide an understanding of the theoretical background and engineering approach to deal with RCS prediction and reduction for naval ships.

He spent 16 years at the University of Michigan Radiation Laboratory conducting RCS measurements of lab models and developing prediction models and moved on to the Georgia Institute of Technology extending similar models and conducting feasibility programs. His entire career has been spent in RCS-related programs. John F.
