Abstract
An apparatus for measuring the orientation of the longitudinal axis of a cavity comprising a signal receiver, a signal processor and analyzer and a cavity axis orientation analyzer. The signal receiver receives a reflected signal resulting from an interaction of multi-frequency irradiating signal(s) with at least one cavity. The irradiating signal may include an electromagnetic or acoustic signal above a cavity dependent cutoff frequency with a randomized or deterministic spectral component. The signal analyzer computes a power spectral density of the reflected signal. The local maxima of the power spectral density are identified and used to determine the cavity longitudinal axis orientation. The cavity may be the bore of a weapon.
