From the angle of a beam-forming, the cross- range focusing principle of the synthetic-aperture radar based on nonsinusoidal waves is studied. The expressions of antenna pattern for both rectangular signa l and Gaussian signal are presented. Compared with the conventional narrow bandw idth SAR whose cross-rang resolution is determined by the carrier frequency, th e cross-range resolution of the nonsinusoidal SAR is affected by the signal ban dwidth.
