A novel dilated fractal nested array is proposed to improve the degrees of freedom on moving platform by combining the sparse fractal array and the dilated nested array. The proposed array can be used in the scenario of large array aperture. The closed-form expression of the sensor positions of the proposed array is presented. The translation factor is given and proved to obtain a fully filled difference coarray of the synthetic array. It is shown that the degree of freedom of the proposed array is greatly enhanced. Meanwhile, the proposed array has large aperture with less mutual coupling.
