Introduction to optical transform image modulation techniques and their application to ESM data processing

Processing methods employing optical transform image modulation techniques (OTIM), have shown that very significant improvements in signal-to-background discrimination and clutter rejection can be achieved for remote sensing applications, and current research shows that these methods can also be incorporated into electro-optic data processing schemes with significant advantages. The capability of OTIM configurations to manipulate signals in several domains simultaneously also brings additional benefits
