Operations in Degraded Visual Environments (DVE) are frequent during military actions due to either natural (poor light, fog, glare, etc.) or man-made (smoke, dust etc.) conditions. These conditions adversely affect the performance of Electro-Optical (EO) sensors by reducing their range of effectiveness in terms of Detection, Recognition and Identification (DRI) and navigation capability, and therefore hamper the situational awareness and safety of the personnel. Against this background, EDA launched a call for tenders (code 19.ESI.NP3.291) for a “Study on EO Sensors Performance Improvement in Degraded Visual Environment (SPIDVE)”, focused on new technologies to improve, model and measure the performances of EO systems in DVE conditions.
