US Patent:
7567205, Jul 28, 2009
Filed:
Sep 18, 2008
Appl. No.:
12/212786
Inventors:
Chul J. Lee - Lexington MA, US
Assignee:
Raytheon Company - Waltham MA
International Classification:
G01S 7/40
G01S 13/00
G06T 15/40
G06T 15/30
G06T 15/50
US Classification:
342169, 342175, 345421, 345423, 345426
Abstract:
In one aspect, a method to generate radar signatures for multiple objects in motion, includes performing a shooting and bouncing (SBR) technique to solve for physical optics and multi-bounce characteristics associated with the objects. Performing the SBR technique includes performing dynamic ray tracing to form an image of an object having surfaces and edges. Performing the dynamic ray tracing includes transforming the object in a common coordinate frame of reference to a centered-body axis frame of reference.

Generating Radar Signatures For Multiple Objects

US Patent:
7592947, Sep 22, 2009
Filed:
Sep 18, 2008
Appl. No.:
12/212787
Inventors:
Chul J. Lee - Lexington MA, US
Assignee:
Raytheon Company - Waltham MA
International Classification:
G01S 13/00
G01S 7/40
G06T 15/40
G06T 15/60
US Classification:
342169, 342159, 342175, 342179, 345421, 345426
Abstract:
In one aspect, a method to generate radar signatures for multiple objects includes performing in parallel a shooting and bouncing (SBR) technique to solve for physical optics and multi-bounce characteristics of a plurality of objects in motion, a physical theory (PTD) technique to solve for material edges of the objects and a incremental length diffraction coefficient (ILDC) to solve for material boss/channel. The method also includes coherently integrating the results from the SBR, PTD and ILDC techniques by frequency and generating the radar cross section (RCS) values of the plurality of objects. Performing the SBR technique includes evaluating rays independently.

Reducing Scattering Center Data Using Multi-Volume Aggregation

View page
US Patent:
7602332, Oct 13, 2009
Filed:
Jun 13, 2008
Appl. No.:
12/138814
Inventors:
Chul J. Lee - Lexington MA, US
Brian J. Harkins - Westford MA, US
Andrew P. Simmons - Andover MA, US
Assignee:
Raytheon Company - Waltham MA
International Classification:
G01S 7/40
G01S 13/00
G06T 15/30
G06T 17/20
G06T 15/40
H03F 1/26
G06F 17/00
US Classification:
342169, 342175, 345421, 345423, 345426, 707101, 702189
Abstract:
In one example, a method to reduce scattering centers (SC) includes receiving a set of SC data points associated with an object in three-dimensional space, partitioning the SC data points into a plurality of volumes, aggregating the SC data points within each volume based on an aggregate threshold and combining the aggregated SC data points associated with each volume to form a reduced set of SC data points. The method also includes comparing the reduced set of SC data points with the received set of SC data points to determine if the reduced set of SC data points meets a set of comparison metrics and if the reduced set of SC data points meets the set of comparison metrics, increasing the size of the volumes and performing another iteration of reducing the SC data points by volume.

Assignee:
Raytheon Company - Waltham MA
International Classification:

US Classification:
342169, 342175, 345421, 345423, 345426, 707101, 702189
Abstract:
A method to reduce scattering centers (SC) includes receiving a set of SC data points representing an object. The method also includes reducing SC data points associated with a first region based on magnitudes of intensity of the SC data points associated with the first region, reducing SC data points associated with a second region based on magnitudes of intensity of the SC data points associated with the second region, combining the reduced SC data points associated with the first region and the second region to form a reduced set of SC data points, comparing the reduced set of SC data points with the received set of SC data points to determine if the reduced set of SC data points meets a set of comparison metrics and if the reduced set of SC data points meets the set of comparison metrics, performing another iteration of the reducing.

Method And Apparatus For Interleaved Gridding In Distributed Multiple Computing For Real-Time Rcs Prediction

View page
US Patent:
7646332, Jan 12, 2010
Filed:
Aug 9, 2007
Appl. No.:
11/889197
Inventors:
Chul J. Lee - Lexington MA, US
Sean T. Price - Marlborough MA, US
Assignee:
Raytheon Company - Waltham MA
International Classification:
G01S 13/00
US Classification:
342 90, 342 92
Abstract:
Apparatus and method for real-time determination of radar cross sections is disclosed using interleaved gridding. Radar cross section calculations are amenable to an implementation on parallel processors wherein the shooting window is subdivided into smaller areal units that are assigned to the parallel processors in an alternating fashion, such that the calculations performed by a single processor are not localized to a single area of the shooting window. As further disclosed, the shooting and bouncing ray technique for calculating radar cross sections is implemented using the apparatus and method disclosed herein.

Rcs Signature Generation For Closely Spaced Multiple Objects Using N-Point Models

View page
US Patent:
7652620, Jan 26, 2010
Filed:
Aug 9, 2007
Appl. No.:
11/889198
Inventors:
Chul J. Lee - Lexington MA, US
Brian J. Harkins - Westford MA, US
Assignee:
Raytheon Company - Waltham MA
International Classification:
G01S 13/00
US Classification:
342195, 342175, 342169
Abstract:
A method and system for analyzing the RCS of an object using N Point signature prediction models is provided. N-point signature prediction models are created for each object in a scenario and stored in lookup tables. Shooting and Bounce trace back techniques are used to determine RCS signatures of multiple objects in modeled scenarios to account for blockage by and coupling phenomena of a scattered field.

International Classification:
G01S 13/00
US Classification:
342169, 342175, 342179, 342421, 342426
Abstract:
In one aspect, a system to generate a radar signature of an object includes electromagnetic processing modules that include a first module including at least one processing unit to perform a shooting and bouncing (SBR) technique to solve for physical optics and multi-bounce characteristics of the object, a second module including a processing unit to perform a physical theory (PTD) technique to solve for material edges of the object and a third module including a processing unit to perform an incremental length diffraction coefficient (ILDC) to solve for material boss/channel. Results from the first, second and third modules are coherently integrated by frequency to generate radar cross section (RCS) values of the object in real-time. Performance of the system is scalable by adding processing units to at least one of the first, second or third modules.
