Adaptive phase compensation for distorted phased array by minimum sidelobe response criteria

Nonpoint sources are used as the beamforming source for distorted phased array antennas. Since adaptive phase compensation is a nonlinear optimization problem, an appropriate solution is found. A noniterative solution is presented which utilizes a priori knowledge about the sidelobe region of the target field, which is the nonilluminated region of a radar illuminator, to find a phase vector which minimizes the array response in that region. An approximate solution of this phase vector can be found by solving a standard adaptive array problem. Computer simulation results are presented to demonstrate the performance of the proposed algorithm.<>
