Electro Optical Pod
The electro optical pod is a type of avionics pod that can house electronic equipment like sensors and cameras.electro optical pod They provide warfighters with situational awareness and targeting capabilities, even in the dark and in adverse weather conditions. They can be installed on land, naval, fixed-wing and rotary-wing platforms. They can also be used for homeland defense and other critical missions.
EO/IR (Electro-Optical/Infrared) systems are used to detect and track enemy targets day or night, in clear or adverse conditions.electro optical pod The technology combines visible and infrared imaging sensors with computing architectures. Combined with active and passive countermeasures, the system provides a complete situational picture for warfighters and the ability to take action to stay ahead of adversaries.
A wide range of EO/IR solutions from Northrop Grumman can be found on military vehicles, aircraft and ground-based platforms.electro optical pod The LITENING advanced targeting pod, for example, is a passive imaging radar that provides long-range precision targeting and threat protection.
The LITENING IR Distributed Aperture System is another EO/IR solution that can be found on manned and unmanned air, land and sea platforms. The EO/IR sensors are capable of providing a 360-degree view of the battlefield, including areas inaccessible to other sensors, while remaining undetected by surface-to-air missiles.
The electro-optical system market is expected to grow in the future, owing to the increasing need for unmanned aerial vehicle surveillance and monitoring systems. The electro-optical sensors are available in a variety of shapes and sizes, including those that are adapted for the needs of specific applications. The most popular types of electro-optical sensor include charge-coupled device TV cameras, laser designators and laser rangefinders.
These systems use a variety of techniques to generate and measure radiation in the optical spectrum, which includes wavelengths from 0.01 to 1,000 micrometres. This part of the electromagnetic spectrum contains infrared radiation, visible light and ultraviolet radiation. Optical switches are one of the most important technologies in electro-optical systems. They can be based on thermal methods that vary the refraction index in one leg of an interferometer to switch a signal, MEMS approaches that involve arrays of micromirrors that can deflect optical signals and piezoelectric beam steering liquid crystals that rotate polarized light based on an electric field.
The technical challenges associated with cooling electro-optical components mounted in a pod residing under the fuselage of an aircraft are complex and challenging to overcome. These include limited access to the pod for external coolant, limited space to house an internal radiator and the need to manage electrical power consumption for cooling.
A mechanical model of the pod's rotating cabin body has been established using MATLAB. The model is able to provide an accurate and precise simulation of the rotational performance. This allows for the design of a lead and lag compensation filter network that can significantly improve the pod's dynamic performance, effectively reduce jitter amplitude and make digital filering easier. The experimental results demonstrate that the proposed filter is able to achieve these goals.
