Popis:	Frequency-invariant arrays are widely used in communication systems, audio processing and radar. For this applications wideband beam steering with FIR-filters is required. The paper presents a fixed frequency-invariant beamforming method. Proposed method allows beam steering and it does not require minimizing functions or the Fourier transform. The proposed approach is based on the usage of frequency properties of arrays and allows finding real coefficients of FIR-filters.
