Near-Field Bistatic RCS (Radar Cross-Section) Measurements. made in the near-field of the object. This technique is an extension of existing planar near-field antenna measurement technology. Planar scanning measurement of monostatic/bistatic RCS by near-field far-field transformation based on fast multipole method near-field radar cross-section (RCS) measurements to the far zone.
planar scanning. Index Terms — Near-field Far-field Transformation, Radar Cross Section (RCS), Fast Multipole Method (FMM) I. INTRODUCTION The radar cross section (RCS) measurement is important for the target’s characterization for both monostatic and bistatic case. Radar cross section (RCS) is one of important EM properties of radar targets.
Its measurement requires long distance to obtain far-field characteristics in higher frequency range such as X-band. Planar scanning near-field measurement combined with near-field far-field (NF-FF) transformation is realized by simple measurement mpcs.online: Shuntaro Omi, Toru Uno, Takuji Arima, Yujiro Kushiyama, Takao Fujii.
Near field measurements require a sensitive and accurate mechanical infrastructure as well as a mathematical In planar scanning, the probe travels on a plane in front of test antenna and complex signal data is saved will help to save time.
Especially in applications in which one doesn’t need exact results, such as a radar. The results of an extensive error analysis on planar near-field measurements are described.
There are also true bistatic radars - radars where the transmitter and receiver are in different locations bistatic radar application Electronic Warfare and Radar Systems Engineering Handbook - Two-Way Radar Equation (Bistatic).
Radar Cross Section Measurements is a valuable source for professional people needing reference material on the measurement of RCS targets both indoors and outdoors. It will be especially useful to aerospace engineers and scientists working with modern radar systems.
Chapter 11 Radar Cross Section (RCS) In this chapter, the phenomenon of target scattering and methods of RCS RCS measurements in the frequency region, where the target Near field RCS, bistatic RCS, and RCS measurements in the Rayleigh region will not be considered since their treatment falls beyond this book™s inte nded scope.
This paper presents a simple and practical method and measurement results of transformation by using the idea of array-factor for direct far-field prediction from the near-field data of antenna and RCS in cylindrical scanning system.
When radiation pattern of an antenna or scattering pattern of radar cross-section (RCS) is measured, its characteristics is usually evaluated in the far-field area. KEYCOM’s product line of radars includes Radar Test Systems (RTS) to evaluate distance accuracy or output, Radar Alignment Systems (RAS) to help you adjust the alignment of radars, and Radar Cross Section (RCS) measurement systems to measure RCS of.
In the 's there was tremendous interest in adapting the compact range for radar cross-section measurements. Originally conceived as a method for testing X and Ku band fire control radars, there had to be significant changes in the compact range in order to make it.
This paper presents a first-principles algorithm for estimating a target’s far-field radar cross section (RCS) and/or far-field image from extreme near-field linear (1- D) or planar (2-D) SAR measurements, such as those collected for flight-line diagnostics of aircraft signatures.
Tilting the receive end wall of a compact range anechoic chamber to improve Radar Cross-Section (RCS) measurements has been a tool of the trade used since the earliest days of anechoic chambers.
A preliminary analysis using geometrical optics (GO) validates this technique. Overview of an image-based technique for predicting far-field radar cross section from near-field measurements Abstract: For the last 18 years, our group has been developing a variety of near-field-to-far-field transformations (NFFFTs) for predicting the far-field (FF) RCS of targets from monostatic near-field (NF) measurements.
Bistatic radar cross sections of targets are computed from field measurements on a cylindrical scan surface placed in the near field of the target.
The measurements are carried out in a radio anechoic chamber with an incident plane-wave field generated by a compact-range reflector. Radar cross-section (RCS) is a measure of the magnitude of the scattered electromagnetic wave from a body relative to the magnitude of the wave incident on the body.
To many people RCS is synonymous with stealth. Stealth technology has become an integral part of all military systems since it was first employed in the s.

Three-dimensional radio frequency imaging techniques have been developed for a variety of near-field applications, including radar cross-section imaging, concealed weapon detection, ground penetrating radar imaging, through-barrier imaging, and nondestructive evaluation.
These methods employ active radar transceivers that operate at various frequency ranges covering a wide range, from less. A physical optics based method is presented for calculation of monostatic Radar Cross-Section (RCS) of a shell-shaped projectile.
