Abstract : This final report documents the continued design, hardware implementation, and testing of an acoustooptic (AO) multichannel adaptive optical processor (MADOP) for application to the cancellation of multipath jamming interference in advance surveillance applications. The work described in this report was performed for the Photonics Center at Rome Laboratory (RL) and represents the third year of Dynetics support on this project. The key program objective of this effort was the integration and testing of the MADOP hardware with the C-band radar testbed at the RL Surveillance and Photonics Directorate. To meet this objective, a number of improvements were made to the MADOP hardware and software, and laboratory testing was performed to ensure correct operation of the system. The successful integration of the MADOP with the C-band radar testbed was achieved, and testing of jammer cancellation in a number of configurations was performed. Performance results included 3O-dB cancellation of narrowband tone jammers and 15- to 20-dB cancellation of wideband (8-MHz)noise jammers.
