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.
