How Phenomenology Affects Image Quality of an EO Payload

A payload is a component that’s deployed to perform a specific function.eo payload For example, a UAV’s optical payload could capture imagery that’s used to gather intelligence about a potential enemy threat.eo payload Optical payloads are essential components that enable military and law enforcement personnel to gather critical data for operational decision making.

Whether they’re used for surveillance, navigation, tracking, or targeting, an eo payload’s ability to accurately deliver critical information is the key to its success.eo payload eo payload That’s why it’s important for an EO/IR sensor designer to understand how the phenomenology of a given target affects image quality.

The eo payload’s environment, including the target, illumination source (including sunlight, moonlight, or artificial illumination), and the atmosphere, all affect the performance of an EO/IR system.eo payload Unlike radar systems, EO/IR sensors are passive, relying on the illumination of their target by sunlight or moonlight, or the target’s own emissions of light.eo payload In addition, the incoming photons must pass through the hostile environment of the atmosphere, which can refract or scatter the rays of light.

This is why it’s important for an EO/IR camera to have multiple bands, so that the system can select the best band for a particular target or mission.eo payload The choice of which band depends on the expected targets and their phenomenology.eo payload For example, a hot missile launch detection requirement may require the use of a specific ultraviolet wavelength, since this is the band in which most of the radiation is reflected, as opposed to the mid- or long-wavelength infrared (MWIR or LWIR) bands, where most of the emission is absorbed.

Once the band is selected, the EO/IR sensor’s design must ensure that the sensor can acquire and process the target’s radiation.eo payload For example, the sensitivity of an EO/IR sensor to reflected or emissive radiation is affected by its size, shape, temperature and coatings, as well as the ambient conditions. This includes the target-background contrast, the intensity of the illumination source, and the operating altitude of the aircraft or vehicle.

Finding the working space where an instrument’s accuracy meets its optimal cost-effectiveness point is a complex task.eo payload To accomplish this, the system engineer needs to fully understand how each figure-of-merit will influence the system’s ability to meet its mission objectives. This includes identifying the various requirements and ranking them according to their impact on the overall mission success. The 3U BAM XRS’s SWaP-optimized architecture increases compute density to reduce footprint and power consumption, while supporting up to 8 front-removable NVMe, SAS, or SATA SSDs for maximum storage capacity, high read/write speeds, reduced latency, and mission-critical data access. This server also delivers advanced security to protect data-at-rest, in-transit and in-use against unauthorized access across hardware, firmware, software, and network stacks. This protection enables warfighters to gain a tactical, strategic and operational advantage over adversaries.
