Design and Fabrication of a Multichannel Adaptive Optical Processor (MADOP)
Abstract
We designed and built a multichannel adaptive optical processor (MADOP) for the purpose of adaptive cancellation of broadband jamming noise in C-Band antenna arrays. The processor operates at an intermediate frequency (IF) of 80 MHz and is designed to provide greater than 30 dB cancellation of two independent 10 MHz bandwidth noise jammers, where multiple reflections of the jamming energy collected in the sidelobes produce multipath delays of up to 5 usec. The MADOP architecture is portable and designed to function as an on-line 'smart filter' which adaptively cancels broadband noise in the sidelobes.
