Abstract
A guided munition system includes a munition body including at least one fluid dynamic control for changing course of the munition body in flight. A seeker onboard the munition body is operatively connected to control the at least one fluid dynamic control. The seeker includes a coded aperture imaging device facing outward from the munition body for image based control for guiding the munition body in flight.
Claims16
A guided munition system comprising:
- a munition body including at least one fluid dynamic control for changing course of the munition body in flight;
- and
- a seeker onboard the munition body operatively connected to control the at least one fluid dynamic control, wherein the seeker includes a coded aperture imaging device facing outward from the munition body for image based control for guiding the munition body in flight,
- wherein the coded aperture imaging device includes a sensor spaced apart from a coded aperture,
- wherein the sensor includes a focal plane array (FPA),
- wherein the FPA is sensitive to short-wave infrared (SWIR) wavelengths,
- wherein the coded aperture includes a pattern of transparent and opaque or reflective areas defined in a mask on the substrate, and
- wherein the coded aperture includes a spatial light modulator (SLM) configured to change the pattern in the mask for situational adaptability.
