A New Frenquency-Domain Imaging for High-maneuverability Bistatic Forward-looking SAR

Bistatic forward-looking SAR is a synthetic aperture radar system with an independently moving transmitter and receiver breaks through the limitations of the conventional monostatic SAR on the forward-looking imaging. However, the existence of a double hyperbola in the bistatic range equation makes the severe two–Dimension (2-D) coupling. Based on the bistatic SAR space geometrical model and the point target spectrum form the series reversion, this paper deals with above problems with the Second-Keystone and the nonlinear chirp scaling (NCS) algorithm. The results of simulation verify the feasibility of the method.
