Abstract:
1. A method for adaptively reducing, in a displacement signal having a value indicative of a measured angular displacement ε between an antenna boresight and an apparent line of sight to a target, a noise signal having a value indicative of an angular error induced by a shift in the target radar centroid so as to provide an output signal having a value indicative of an estimate {circumflex over (ε)} of a true angular displacement signal between the antenna boresight and a true line of sight to the target, comprising the steps of: providing a series of sequential samples of said displacement signal each having a respective sample value ε generating in response to each sample value ε generating in response to each sample value ε multiplying each sample value ε summing the last N weighted sample values ε and providing said output signal having a value corresponding to the sum of the last N weighted sample values ε
