A switched pattern radar antenna array
Abstract
A procedure to design a switched pattern antenna array is developed and demonstrated on a 16- and eight-element array. The variable spacing of elements allows a reduction of the number of switchable elements to a minimum as well as a reduction of the sidelobes of the effective pattern. Based on this design, an eight-element prototype array was built and tested. Measurements demonstrate the feasibility of the pattern switching concept for improved sidelobe performance.
