- Abstract
- A block diagram of an adaptive non-recursive rejector filter of the 3rd order is presented, including cascading connection of an auto-compensator of the Doppler phase of passive interference, a rejector link of the 1st order and a rejector link of the 2nd order. The weighting coefficient of the 2nd-order link is adapted based on the correlation properties of the cutting residues of the 1st-order link. A method for analyzing filters of this type based on the asymptotic properties of estimating the maximum likelihood of the correlation coefficient of the output samples of the 1st-order link interference is proposed.
