Abstract: A system and method for registering a test image with a reference image requires decimation of both images to create corresponding image pyramids. A Log-Polar Transformation (LPT) is then applied to corresponding pixels from the same highest levels of the respective pyramids. Next, these pixels are manipulated to establish a Normalized Correlation Coefficient (NCC) for their respective correlations. Approximately the highest 10% of correlated pixels are then retained to identify related pixels in the next lower level of their respective pyramids. Again, LPT is applied to these related pixels and they, in turn, are manipulated to establish NCC correlations for identifying pixels to be retained. This process is successively accomplished for each lower level of the pyramid until the lowest levels (i.e. the test image and the reference image) are correlated and used for registration of the test image.

Abstract: A method correlates audit information in a multi-tenant computing infrastructure. The method leverages a user's authentication to the infrastructure, such as via federated single sign-on (F-SSO) from an identity provider. Preferably, the user's tenant identifier in the environment is derived based on identity information obtained during the F-SSO exchange. This tenant identifier is propagated to one or more other components in the infrastructure that are accessed by the user. As audit event from multiple components in the computing infrastructure are generated, these audit events are annotated with the tenant identifier and stored in an audit repository. In response to a request to view the tenant's audit data, a collection of tenant-specific audit events are then retrieved from the audit repository and displayed in a single tenant view. This approach ensures that audit event information is not leaked inadvertently between tenants.

Abstract: A hybrid radar receiver includes an antenna array for receiving an input signal having a radar signal from a signal emitter. Each array element outputs an analog signal on a respective data channel. For each data channel, an activatable A/D converter is provided. A dedicated hardware circuit, which typically includes a detector/log video amplifier that is coupled to a threshold/pulse digitizer, is included to determine when a radar pulse is being received. When the circuit determines that a pulse is being received, the circuit activates each A/D converter to generate a digital signal on each channel. When a pulse is not currently being received, the circuit deactivates each A/D converter and digital signals are not produced. Pulse parameter(s) generated by the hardware circuit and the digital signals on each channel are sent to a software equipped processor which implements a signal emitter identification algorithm.

Abstract: A radar system and method for detecting targets using pulse-compressed signals is disclosed. In one application, the systems and methods can be used to detect one or more relatively small targets whose pulse-compressed signals are masked by the time-sidelobes of a larger target's return signal. The method includes an iterative, detect-and-subtract signal algorithm that processes the post-compressed signal to detect multiple targets. Specifically the processing algorithm operates on the post-compressed signal to identify a point spread function (PSF) that corresponds to the relatively large target. Once identified, the PSF corresponding to the largest target in the post-compressed signal is subtracted from the post-compressed signal to generate a residual signal. This residual signal, in turn, includes the PSFs for the other targets. This process of identifying and subtracting the PSF of the largest target in the residual signal is then repeated until all targets are detected.

Abstract: Systems and methods for detecting targets using pulse-compressed radar signals are disclosed. In one application, relatively small targets that are masked by the time-sidelobes of a larger target's return signal can be detected. The methods include a signal expansion type algorithm that is used to process the pulse-compressed return signal. Specifically, a generalized Fourier expansion expression having a summation of PSF terms is used to expand the pulse-compressed signal. Each term represents a respective target and includes a point spread function and a complex coefficient. The signal expansion procedure can be used to determine a set of optimum complex coefficients, with one coefficient for each range bin. Doppler frequency can be used together with range to optimize the complex coefficients. Next, targets are detected by analyzing each range bin to determine whether the corresponding complex coefficient has an absolute magnitude greater than a pre-determined threshold.

Abstract: A data processing system comprising at least two operating systems (OS1, OS2) for virtual machines, a supervisory operating system, i.e., a control program (CP) for controlling the operating systems, control registers (CR0, CR1, ---) and an extended control register (ECR) having a special bit. When a control register operating instruction (LCTL or STCTL) is executed by one of the operating systems, the special bit has a first value and the operating system directly accesses the control register. When the other of the operating systems attempts to execute such a control register operating instruction, the special bit has a second value and an interruption is generated in the supervisory operating system.

Abstract: This invention relates to a register and more specifically to register control in a data processing system. In general, a number of control registers are theoretically required that is less than the maximum number which can be designated, and only the required number of registers are mounted as hardware. In order to add functions or to provide compatibility with other systems, it is sometimes required to use a register that is not mounted as hardware, or to use the registers mounted as hardware for conflicting purposes. Virtual registers are accordingly provided for at address locations in the memory of the processing system. However, if only the registers to be added are thusly provided for in the memory, the instructions must be executed by distinguishing between register access and memory access, in accordance with register number, etc. Thus, this invention provides a number of virtual registers for instance equal to the number that can be designated.

Dummy cycles for a number of cycles having a processing time equal to the desired waiting time are generated by a dummy instruction. A timing control system is disclosed which is especially suitable for a micro-program system of a pipeline control system.
