The Intelligent Missile Seeker (IMS)
The IMS program intended to demonstrate the use of spectral imaging in a missile seeker. The objective was to combine spatial and spectral analyses techniques for target/decoy discrimination. As a part of the program a dual VNIR/SWIR imaging spectrometer was built. Spectral signatures of various airborne targets and various IR decoys and countermeasures (CM) were analyzed in order to assess the potential discrimination in real time operation. Target signatures were both measured and obtained via simulation.The sensors comprised of:
| Pushbroom system
|| OPTICS: Common 6" Cassagrain telescope, with a dichroic
beam splitter sending SWIR radiation to one system and
reflecting VNIR to the other.
|| VNIR system
| SWIR system
| Data acquisition: interface to a PC via a frame grabber
In the field experiment, the IMS sensor has collected spectra of various commercial airplanes during takeoff and landing, in a non imaging mode (stationary, with no push broom operations).
The IMS sensor was delivered to the Air Force, Wright Laboratories, Armament Development Directorate in 1994
