Paper Abstract

Acoustooptic matched filter is capable of processing short, wideband chirps. But due to generating process peculiarities, middle frequency, slope and convexity of instant frequency function are fluctuating. To implement electronic tuning of impulse response, AOMF architecture was completed with controllable liquid-crystal phase mask. The paper presents mathematical models for both fluctuating chirp signal and tunable acousto-optic matched filter. Adaption algorithm was developed for impulse response matching with parameters of chirps being processed.
