Abstract
Many papers have investigated phased array radars beam-forming so far. In these papers the power at a specific point of interest is written by a combination of transmitted power by means of each antenna. In this paper we will introduce a new approach which will use of cross correlation matric like MIMO radars to define beam-pattern of array and then by introducing an optimization problem to steering the available power at desire directions, it is shown that with an approach to optimum choosing of antenna placement, it is possible to concentrate the transmitter power on desire direction better than conventional phased array antennas with half wave length spacing. It should be say that some papers have investigated non uniform arrays but those papers usually use of multiple of half wave length in their elements spacing and in addition their approach to choosing these spaces is different and pretty more complicated from presented approach. Simulation is performed to analyze the presented algorithm and compare it's performance with conventional phased arrays with half wave length spacing for linear and planar array. MATLAB software is being employed for simulations.
