Automatic Target Hand-Off for Non-Compatible Imaging Systems.

Abstract

The problem of automatic hand-off of a target from a precision pointing and tracking system (PTS) to an imaging missile seeker using non-compatible imaging systems is considered in this report. The approach taken is to develop preprocessing algorithms which transform the input video signals to a compatible format for input to a binary correlation system. The types of imaging systems considered are a high resolution day TV PTS for target acquisition and a low resolution Infra-Red Imaging Seeker (IRIS) for the missile system. The approach taken is to study the effects on the correlation system of a number of preprocessing algorithms so that trade-offs of each can be presented. The results of implementing the preprocessing algorithms in a correlation system simulation are given and explained. The effects of differing sensor characteristics on the correlation function and the acceptance/rejection threshold are given. A preprocessing algorithm using edge detection is chosen and the advantages and disadvantages are listed. (Author)
