Radar Cross Section (RCS)
Radar Cross Section or RCS measurements have become increasingly important to military customers worldwide. RCS is the projected area of a sphere that has the same radar return as the target. The power received by a radar for a target indicates how well the radar can detect or track that target. For this reason, there is an ongoing effort to reduce the RCS of such objects as missiles, ships, tanks and aircraft.
MI Technologies has designed, constructed and fielded RCS systems for its U.S. and International military customers for many years. The MI-350 Advanced Microwave Measurement System, together with its MI-3001 Data Acquisition and Analysis Workstation, is easily configured to take RCS measurements using the optional MI-3048 RCS Analysis Software.
RCS measurements fall into two categories, evaluation and diagnosis.
|Evaluation consists of measuring the "whole body" RCS of a target at a particular frequency from various angles to determine how well a particular radar will see the target. This measurement normally is used to transmit a single frequency toward the target in order to sample the return. The target is rotated by one or more axes to determine which observation angle presents the highest return.||The goal of diagnosis is to obtain the returns caused by the targets' components (wings, fuselage, engines, etc.). With this information, an object's design can be changed to reduce its RCS signature. High-resolution images of the down range and cross range response of an object are required in order to perform diagnosis measurements. Here, the target is rotated as in evaluation measurement with the addition of being illuminated with a wideband signal at each aspect angle.|
RCS measurements can be obtained in a variety of test configurations. MI Technologies has experience with compact ranges, outdoor far-field test ranges and indoor far-field anechoic chambers supplied with compact range equipment. While the type of facility used impacts the types of measurements that can be performed, MI Technologies has the experience and the technical know-how to design, install and operate the most efficient RCS facility to meet your needs.
MI-3048 RCS Analysis
The RCS analysis software provides the capability to process data acquired in an RCS acquisition. Functions are provided to compensate for background subtraction and target calibration. The corrected data can be processed to generate various outputs such as RCS versus frequency, aspect; RCS versus downrange, aspect; cross-range; focused/unfocussed ISAR imaging; temporal doppler, and range walk among others.
MI-840 RCS Rotators are highly engineered azimuth-over-elevation positioning systems with a very compact size and extreme torque density. They are used in conjunction with our MI-830 Family of RCS Pylons to support various targets for the purpose of Radar Cross Section testing.
The MI-830 Family of RCS Pylons provide safe and reliable target support for low-observable and RCS test and measurements. They cover a wide range of heights and boast load capacities up to 30,000 lbs (13,608 kg).
