Filed:

Sep 10, 2008

Appl. No.:

12/207810

Inventors:

William H. Davis - Columbia City IN, US
John H. VanPatten - Columbia City IN, US
Lee A. McMillan - Fort Wayne IN, US

Assignee:

Raytheon Company - Waltham MA

International Classification:

H04B 17/00

US Classification:

455 6713, 455 631, 455 73, 375227, 375285

Abstract:

In one aspect, a method to simulate performance of a communication system includes providing a list of interference components to a user, receiving from the user selections of interference components from the list of the interference components, performing an analysis based on the user selections of the interference components and rendering a result of the analysis.

Appl. No.:

13/475233

Inventors:

William H. Davis - Columbia City IN, US
John H. VanPatten - Columbia City IN, US

Lee A. McMillan - Fort Wayne IN, US

Assignee:

Raytheon Corporation - Waltham MA

International Classification:

G01S 7/38

US Classification:

342 14

Abstract:

Disclosed subject matter relates to techniques for predicting jamming effectiveness. In one approach, platform models and propagation models are used to predict maximum threat communication range when jamming is used and when jamming is not used. The maximum range information may then be used to calculate jammer effectiveness. In another approach, probability-based techniques are used to predict jamming effectiveness for a system of interest.

Appl. No.:

13/475244

Inventors:

William H. Davis - Columbia City IN, US
John H. VanPatten - Columbia City IN, US

Assignee:

Raytheon Company - Waltham MA

International Classification:

H01Q 3/00

US Classification:

342360

Abstract:

Methods and systems are disclosed for performing energy-on-target simulations for targeted regions to predict power or energy levels incident within the targeted region resulting from transmissions of a specific transmitting platform. Models may be used of a transmitting platform, a receiving platform, and a channel between the transmitting platform and the receiving platform to perform the simulation. In some embodiments, a plot may be generated of the energy-on-target results.

International Classification:

H04B 17/00

US Classification:

4552262

Abstract:

Systems and methods are disclosed to analyze and predict the interference susceptibility of receiver designs. In some implementations, the systems and methods may be used during a receiver design phase to predict how well a receiver design will perform in the presence of certain types of signals in a deployment region of a receiver. The systems and methods may allow potential shortcomings in a receiver design affecting interference susceptibility to be identified and remedied before any actual receiver hardware is constructed, thereby reducing costs typically associated with complex hardware redesign efforts.
