Radar Cross Section (RCS) measurements are quintessential in understanding target scattering phenomenon. The reduced RCS of modern weapons systems stresses the capability of current RCS measurement ranges. A limiting factor that has recently become more significant is the electromagnetic coupling between a test target and the mounting hardware used to support it and control its orientation during the RCS measurement. Equally important is the electromagnetic coupling between the RCS calibration artifact and its mount, which provides an opportunity to explore the coupling phenomena without delving into operationally sensitive areas. The primary research goal was to characterize the interaction between a calibration artifact and its mounting apparatus when measuring the RCS of the calibration artifact as part of a larger RCS measurement process. Standard methods, such as vector background subtraction, do not account for this interaction. By understanding the interaction term, a more accurate measurement of target RCS may be obtained. Through careful characterization of the interaction, an additional term can be included in the vector background subtraction equation to reduce the level of uncertainty. Two techniques were developed to isolate and characterize the interaction between the target and mount. The first involves evaluating the far- zone fields scattered by the target under two conditions: the target alone and then the target with mounting hardware present. The fields are then coherently subtracted to isolate the interaction. This process was validated with measurements and computational results. The second technique involves evaluating fields on the target surface under the aforementioned conditions, which are subsequently subtracted from one another and radiated to the far-field.

This guide explains how radar cross section (RCS) is measured and tested with good measurement practice including assuring that the electromagnetic test environment is optimized for the particular object being measured. It also provides basic and advanced information on instrumentation systems, test range design, and measurement technology.

Excerpt from Uncertainty Analysis of Radar Cross Section Calibrations at Etcheron Valley Range The Etcheron Valley Range (evr) measures radar cross section of various targets provided by United States military and civilian customers. The evr currently Operates coherent ros measurement systems capable of measuring in the vhf, uhf, L, S, C, X, Ku and Ka bands (see Appendix A, Table a.i). The North 40 look - down slant range and the South 40 outdoor bounce range (see Figures are two fully operational sytems. Typical targets measured on these ranges are unmanned aerial vehicles, airplane components, air craft models and components, ship models and components, missiles and tactical ballistic missiles, very low - observable (vlo) articles, reentry vehicles, ground vehicles, rockets and rocket plumes. The North 40 range can also be used to simulate the ocean environment for measuring the ros of ship models and components.

This thesis develops a minimum range criterion for radar cross-section measurements by neglecting the phase of the incident field at the target and considering only the amplitude distribution. In contrast to the traditional minimum range criterion, developed for a flat target characterized by specular reflection, the target examined in this thesis is characterized by a number of independent point scatterers located on the target surface. Instead of enforcing point by point accuracy, accuracy of the average target RCS is required, averaging over a number of measurements. The location of the point scatterers on the target are described probabilistically; the expected average measured RCS versus target range is calculated, and compared to results of a Monte-Carlo simulation. The traditional minimum range criterion is compared to the new minimum range criterion. The traditional minimum range criterion, based on phase uniformity across the target, requires minimum measurement ranges that are much larger than those ranges dictated by the new minimum range criterion for targets dominated by point scattering.
