Abstract
Null steering or null creation in a desired direction is of interest in various long-range communication applications. It requires the calculation of optimized complex weightings for the entire array to steer the main beam in the direction of the desired signal and create nulls in the direction of noise signals. These weightings can be calculated easily by considering imaginary narrow beam pattern rather than actual elemental pattern as basis function for the calculation of the array pattern where the weightings of narrow spot beams and the elemental beams are discrete Fourier transform (DFT) pairs. In this paper a DFT based synthesis technique to generate broad nulls in desired direction in rectangular phased array antennas is presented.
