Abstract
A system of enhancing target detection in a polarization modulated signaling system for detecting targets through one or more given media. A polarization modulated signal is generated and transmitted in the given medium which is the complex conjugate of the polarization modulated response over time of the combined medium and target. The wave equation for transmission through the medium, reflectance from the target and transmission through the one or more given media, is solved and the polarization modulation of the polarization modulated signal is adjusted to match the polarization response over time for maximum propagation through the one or more given media and maximum reflectance from the target over time.
