摘要：

Bistatic synthetic aperture radar (BiSAR), which can break through the limitations of the conventional monostatic SAR on forward-looking imaging, continues to gain in significance due to a variety of applications, like the missile terminal guidance. To improve Doppler resolution and to avoid azimuth ambiguities of the missile-borne SAR, an extended nonlinear chirp scaling (NLCS) algorithm for the forward-looking missile-borne bistatic SAR (FLMB-SAR) is proposed in this paper. Based on the novel algorithm and the bistatic configuration with a stationary transmitter and a forward-looking missile-borne receiver, the missile-borne SAR not only can image the forward-looking terrain of the targets but also plays sufficient role in navigation. Finally, the simulation results are exhibited to validate the correctness of the analysis and prove the two-dimensional (2-D) imaging ability of the FLMB-SAR.
