Performance evaluation of nonlinear filters on impact point prediction of ballistic targets

A simple nonlinear filter construction and performance evaluation method is described and illustrated on several examples by comparing it to more complex nonlinear filter schemes. In the new method, the filter gain is a precomputed, deterministic quantity (possibly a constant) and, the filter’s performance is (approximately) described by deterministic differential equations which can be solved off-line.

Scanning Electron

The scanning electron microscope (SEM) builds up an image by sampling contiguous sub-volumes near the surface of the specimen. A fine electron beam selectively excites each sub-volume and then the intensity of some resulting signal is measured. The spatial resolution of images made using such a process is limited by at least three factors. Two of these determine the size of the interaction volume: the size of the electron probe and the extent to which detectable signal is excited from locations remote from the beam impact point. A third limitation emerges from the fact that the probing beam is composed of a finite number of discrete particles and therefore that the accuracy with which any detectable signal can be measured is limited by Poisson statistics applied to this number (or to the number of events actually detected if this is smaller).
