DESCRIPTION
Our Federal Government Cleint is looking for:
TITLE: Computer-Aided Design Modelling of Complex Targets
BACKGROUND:
The Radar Applications and Space Technologies Section at Defence Research and Development Canada – Ottawa is developing algorithms for the exploitation of data from airborne and spaceborne polarimetric synthetic aperture radar (PolSAR). Current PolSAR activities include development of polarimetric SAR ship detection and classification algorithms. The work focus for this contract is to convert the generic CAD (Computer-Aided Design) model format of ships and non-canonical objects to a model format suitable for the existing Electro-Magnetic simulation tools (e.g., FACETS ) to be applied for radar image and RCS computations.
TASKS:
1) Meet with the Scientific Authority (SA) to discuss and refine requirements, and to determine how these requirements can best be met;
2) Using Rhinoceros-3D to transform polygon faceted surfaces into curved-surface NURBS (Non Uniform Rational B-Splines),
3) Using MSC PATRAN to convert curved-surface models into parametric feature-based models,
4) Perform the required classifications in FACETS EM code using the CAD models for target simulations,
5) Identifying and nominating double-bounce and triple-bounce surfaces on the CAD models,
6) Converting surfaces to dielectric material type where applicable and including ground-plane interaction with target in the CAD models,
7) In case there are complications during the conversion or radar cross-section signature computations, modify the original Rhinoceros CAD model.
GOVERNMENT FURNISHED EQUIPMENTS: DRDC Ottawa will provide specialty CAD software, PATRAN and an electromagnetic computer code FACETS on-site to carry out the required tasks.
REQUIREMENTS:
The minimum experience listed below relates directly to using CAD tools for carrying out the tasks 1 to 7 above:
Minimum college diploma in graphics design and mechanical drawing, Minimum 4 years of experience with Rhinoceros and NURBS conversion applications, Minimum 3 years of experience with MSC PATRAN application, Minimum 2 years of experience working with electromagnetic computational software (e.g. FACETS) Minimum 5 years of experience with general CAD tools and related conversion and formatting applications, SECURITY REQUIREMENTS: enhanced reliability clearance.
TRAVEL AND LIVING: There will be no requirement for Travel & Living in completing this requirement
WORK LOCATIONS:Part of the work will be performed on-site at DRDC Ottawa where specialty computer software can be accessed. Part of the work will be carried out at the Contractor’s own premises.
PERIOD OF CONTRACT:Start date: Upon contract award.End date: December 31, 2009.
DELIVERABLES: CAD model files in IGES, RHINO 3dm, PATRAN db or FACETS pdf format, where applicable, will be delivered as finished products relating to the tasks listed above. No written reports are required.
