The invention provides a method and an arrangement for filtering or pre-processing most any type of multivariate data exemplified by NIR or NMR spectra measured on samples in order to remove systematic noise such as base-line variation and multiplicative scatter effects. This is accomplished by differentiating the spectra to first or second derivatives, by Multiplicative Signal Correction (MSC), or by similar filtering methods. The pre-processing may, however, also remove information from the spectra, as well as other multiple measurement arrays, regarding (Y) (the response variables). Provided is a variant of PLS that can be used to achieve a signal correction that is as close to orthogonal as possible to a given (y) vector or (Y) matrix. Hence, ensuring that the signal correction removes as little information as possible regarding (Y). A filter according to the present invention is named Orthogonal Partial Least Squares (OPLS).

The invention relates to a maneuvering target high-resolution ISAR sub-aperture fusion imaging method. The method includes the following steps: S1. a radar transmits a chirp signal and receives echo data in a dechirping mode; S2. Translation compensation is performed on the echo data, dividing the echo data in a large-angle observation form into a plurality of pieces of sub-aperture echo data; or existing sub-angles having a plurality of angles of view/a multi-base ISARs are used as sub-aperture echo data; S3. Target rotation parameters are estimated based on an image sharpening degree maximization method, and the azimuth resolution of each sub-aperture image is estimated; S4. a sparse signal processing method is utilized to correct the resolution of each sub-aperture image; and S5. geometric registration and fusion are performed on each sub-aperture image, thereby realizing high-resolution ISAR sub-aperture fusion imaging. The maneuvering target high-resolution ISAR sub-aperture fusion imaging method provided by the invention can solve the problem of poor imaging quality caused by target maneuverability under the circumstance of a large angle, multiple angles of view or a multi-base ISAR, and improves capabilities of identifying and explaining unknown target ISAR imaging.

A system for heart performance characterization and abnormality detection includes an interface for receiving sampled data representing an electrical signal indicating electrical activity of a patient heart over multiple heart beat cycles and for receiving a pace signal indicating occurrence of a heart pace pulse applied to the heart. A signal processor uses the received sampled data and pace signal in calculating, a first signal characteristic value comprising a time interval between occurrence of the pace pulse and a cardiac cycle characteristic and a second signal characteristic comprising an average of the time intervals determined over a multiple heart cycles. A comparator compares at least one of the first and second characteristic values with a threshold value to provide a comparison indicator. A patient monitor generates an alert message associated with the threshold in response to the comparison indicator indicating a calculated signal characteristic value exceeds the threshold value.
