Sets of Waveform and Mismatched Filter Pairs for Clutter Suppression in Marine Radar Application

Abstract

Sets of waveform and mismatched filter pairs are used. On the contrary with Golays matched waveform filter pair the mismatched waveform filter pair does exist for all N (number pulses in waveform). Using corresponding shapes of filter good Doppler tolerance may be provided. This property together with a good range side-lobs level suppression makes it's attractable for use in marine radar.

Synthesis of Binary Group-Complementary Sequences

“…Generalized complementary sequences were considered in [4]. These generalized complementary sequences, named groupcomplementary sequences, may contain more than two sequences and find their applications in radar [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] and communication [20,21]. The properties of complementary sequences and their relation to other types of codes were investigated by several authors in [3,4,5,6,7,22] and in survey article [22].…”
