Investigation of a spatial-temporal filter in the case of the processing of broadband signals

A method for the synthesis of spatial-temporal filters is proposed which assures suppression of broadband signals from prescribed directions. The proposed method makes possible a considerable reduction in the number of necessary mathematical operations in the computation of weight coefficients as compared with previous methods. This is achieved by means of a simplified procedure of zero control for the linear antenna array for the selected frequency components, as well as by means of an independent computation of the weight coefficients on each element. The structure of the filter can be analyzed on the basis of the dependence of the suppression depth of noise sources on the value of the delay element and the number of taps on an array element.
