Abstract
The jammer suppression algorithm is written specifically for array radars in which the number of array elements K is very large compared with the number of jammers L the radar is designed to suppress. It separates the quiescent weight vector into two components. The component orthogonal to a set of M noise sample vectors is renormalized to unit length and identified as the adapted weight vector. The algorithm is effective in the suppression of many types of jammmers, including repeater and blinker jammers. The number of noise samples required in the construction of the adapted weight vector is usually very small. In the special case of L monotone jammers, for example, a choice M=L usually reduces output jammer power to a few dB above the white noise background. It is permissible to set M
