Abstract The formula is presented to solve the singular problem of Ludwig’s algorithm. And vector field is used as interface to combine Physical Optics (PO) and Uniform Theory of Diffraction (UTD) and MOment Method (MOM) to calculate the airborne antenna. The character of the array is analyzed with MOM, large and simple parts of the plane are analyzed with UTD, and the complex parts are analyzed with PO. The results show that combing these three methods together is a good way for the pattern prediction of the airborne slot array.
