Estimating the term…
Apparatus and method for improving detection of targets in a radar system that employs adaptive filtering. A nonhomogeneity detector eliminates nonhomogeneous signals from the population of signals received. An adaptive filter weight controller estimates covariance matrices from only homogenous signals. Thus the apparatus and method improves the probability of detecting the presence or absence of a target at the same time that it decreases the probability of a false alarm by improving the performance of an adaptive filter. Though developed for airborne radar, the apparatus and method may be applied to the processing of any image.
In a system for processing signals, a method, for identifying a one of presence and absence of at least one potential target, comprising the steps of:
Apparatus for processing signals from which to identify a one of presence and absence of at least one potential target, which comprises:
Apparatus for dividing a plurality of multidimensional signals into at least two groups based on covariance of said signals, wherein said covariance is among all members of said plurality of signals.
