Current Hypersonic projectile systems are being developed to collide with an enemy ballistic missile. Cyan Systems has developed very high definition EOIR imagers, that have the potential to create a compact precision strike weapon. The Hypersonic Electro Optical Seeker System (HEOSS) represents a revolutionary capability for Hypersonic Vehicles (HSVs) because of the extreme resolution, sensitivity, and short integration, kilo-hertz window frame rates which enables superior accurate aimpoint required in a very high velocity seeker. In order to successfully develop a compact seeker for Hypervelocity platforms, designs must address key challenges for high resolution, including aero-thermal issues for the seeker and window/aperture, compensation of local turbulence distortion and window heating effects on sensor.
