|The Physical Object|
Scientists and engineers have had to measure or estimate the radar cross section (RCS) of objects ever since the invention of radar. This guide explains how RCS is typically measured on test ranges, and how testing may be tailored to meet specific requirements. The book provides basic and advanced information on instrumentation systems, test range design, and . From inside the book.

What does RCSR stand for? RCSR stands for Radar Cross Section Reduction (Techniques) Suggest new definition. This definition appears rarely and is found in the following Acronym Finder categories: Science, medicine, engineering, etc. See other definitions of RCSR. In Fig. 1, S (t) represents the transmitted radar signal, S C (t) is the cancellation signal, e (t 1) is the jamming signal. τ 1 is the time delay between the time when the radar signal is received and the time when the cancellation signal is transmitted. Δτ is the jammer processing delay time. The functions of this system mainly include two parts: on one hand, after down conversation, the Cited by:

Calhoun: The NPS Institutional Archive Theses and Dissertations Thesis Collection Investigation of high frequency ship radar cross section reduction by means of shaping. Radar cross-section (RCS) is a measure of how detectable an object is by radar. 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 book discusses the active and passive radar cross section (RCS) estimation and techniques to examine the low observable aerospace platforms.
It begins with the fundamentals of RCS, followed by the dielectric, magnetic and metamaterials parameters of the constituent materials and then elaborates various methods and the emerging by: The radar cross section (RCS) measure of a naval ship is one of the important design features when considering the survivability in hostile environments.
Therefore, various techniques, such as shaping, shielding and applying radar absorbing materials, are applied to RCS reduction of the object naval ship.
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. for radar cross section reduction. The incident radar phase, amplitude, frequency, polarization, radar space position and waveform characteristics are accurately and quickly measured on the target platform by SPC, and a reconnaissance receiver.
The characteristics of target reflection that correspond to the incident radar waveform. for radar cross section reduction (RCSR); shaping, radar absorbing mat erials, passive cancellation and active ca ncellation. Of the four, the use of shaping and r adar absorbers areAuthor: Hakan Ucar.

A software system for a complex object scattering analysis, named SYSCOS, has been developed for a systematic radar cross section (RCS) analysis and reduction design.
The system is based on the high frequency analysis methods of physical optics, geometrical optics, and physical theory of diffraction, which are suitable for RCS analysis of Cited by: 1. 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 by: 7. Introduction to Radar Cross Section Reduction Introduction The concept of stealth or radar cross section (RCS) reduction and control has been a topic of interest since World War II.
