Abstract: An apparatus and method using a program protection engineering (P2E) toolkit to provide program protection engineering, security management, and report preparation for sensitive and classified projects. The P2E toolkit is an implementation of security policies, procedures, and methodologies associated with acquisition programs. Acquisition programs may range from large-scale classified systems for the government to sensitive corporate acquisition programs focusing on company proprietary or intellectual property issues. Specifically, the P2E toolkit provides end-to-end program protection engineering, security management, and report preparation for sensitive and classified programs throughout the program lifecycle, and assists security professionals and program managers to make appropriate decisions to protect their acquisition programs from compromise due to foreign intelligence threats or corporate/industrial espionage.

Abstract: First and second AC electric sources modulate a coherent wave constant amplitude optical beam. An optical waveguide arrangement responsive to the optical wave, includes first and second pairs of electrodes respectively connected to be responsive to the first and second AC sources. The electrode pairs are capacitively coupled to first and second portions of the optical waveguide arrangement for amplitude modulating the optical wave propagating in the first and second portions in accordance with the first and second AC sources, respectively. The first and second portions of the optical waveguide arrangement are coupled together so that the waves modulated in the first and second portions are combined to derive a third coherent modulated optical wave.

Abstract: An optically defractive medium of a Bragg cell has a moving grating induced therein in response to acoustic waves propagating in the medium. First and second electro-acoustic transducers coupled to the medium launch first and second acoustic waves toward each other in response to electric excitation of the transducers to produce a moving grating having an amplitude proportional to the difference in the amplitude of the first and second acoustic waves. A laser illuminates the medium and an optical detector array including plural individual detector elements responds to optical energy from the source, as modulated by the moving grating. A processor responds to the detector elements to derive an indication of time difference of arrival of first and second electric signals that respectively drive the first and second transducers.

Abstract: The satellite coverage problem involves the determination of a given satellite's in-view and out-of-view times and durations for a given ground point. To perform global coverage, the planet is divided into an even grid in spherical coordinates. Assuming a minimum elevation from the ground to the satellite of interest, the satellite's ground footprint longitude width is determined analytically at a given latitude. Ignoring planetary triaxality, the footprint is assumed to be east-west symmetric. All grid points with the footprint satisfy line-of-sight geometric constraints. The process is repeated for every satellite at every time point, and coverage statistics are generated over the grid at the end.

Abstract: A remote data collection system, which may be used in a vehicle such as an aircraft or a ground vehicle, includes a directional sensor, such as one or more cameras, for sensing a characteristic of interest and providing sensor data. The system further includes a global positioning system (GPS) receiver for providing GPS data representative of the position of the sensor, an inertial measurement unit (IMU) for providing IMU data representative of the attitude of the sensor, a processing unit and a storage unit. The processing unit determines geographic data referenced to the sensor data in response to the GPS data and the IMU data. The processing unit may utilize an error model to determine IMU errors which may be used in determining the geographic data with high accuracy. The sensor data and the geographic data are stored in the data storage unit for subsequent use. The system may include a stabilized platform on which the sensor and the IMU are mounted.

Abstract: The present invention provides an image data registration system and method of storing a first data set of three-dimensional image data associated with a predetermined portion of an object with reference to a first coordinate frame; obtaining and storing a second data set of three-dimensional image data associated with a surface of the predetermined portion of the object with reference to a second coordinate frame; and registering the first data set and the second data set to generate a matched image data set in which the first coordinate frame is aligned with the second coordinate frame.
