Abstract In the case that the jammer platform rotates or is pointed in all different directions, a new scenario consisting of orthogonal multiple elements is presented, and then rigorous mathematical derivation and theoretic analysis are given for the new scenario. The closed-form solutions for angle error are derived, which is useful in mathematics for comparison and evaluation. Meanwhile, it provides theoretical references for optimizing the performance. Through comparisons, the nature of mathematics for orthogonal arrays and linear arrangement of jamming elements are proposed. Using stability factor and angle error that the systems in the same radar pointing angle as index, mathematics analysis and example are made to prove that the new scenario outperforms the conventional one in the aspect of stability and effectivity.
