Abstract

Abstract

Due to the variational flight path during the diving maneuver, the range function of the point target for the missile-borne SAR becomes complicated. Thus, a new imaging method is proposed in this paper. Firstly, the target range function is expanded to a quartic polynomial. Secondly, the stationary point is solved via the Cardanos formula, and then the tow-dimensional spectrum is obtained, based on which a new imaging algorithm is derived. Finally, the simulation result of the point targets shows that the algorithm proposed is effective to give a high resolution imagery with the entire aperture of the missile-borne SAR than the traditional method.
