Abstract

The correlation performances of four different types of joint- transform correlators (JTCs) are investigated in a non- cooperative situation when the target image is cluttered with scene noise and present under poor illumination condition. Computer simulation and experimental results are provided. The JTC based on modified fringe-adjusted filter performs better in such a combined situation.
