Abstract: Based on a linear phased array antenna, sector nulling using phase-only control is analyzed by using a fast algorithm and a partly controlling method. And it can be modeled to a constrained discrete nonlinear optimization problem. An experiment is performed to verify the algorithm and the method. -
