The wideband bistatic echo of a precession cone-shaped target is modeled and the procession parameter estimation method is proposed based on the monostatic and bistatic high resolution range profile (HRRP) sequences and extended Hough transform.Then
the bistatic ISAR imaging model of precession target is introduced and the optimum imaging time is derived.By selecting the optimum bistatic HRRPs
a clear bistatic ISAR is obtained via the classical fast Fourier transform processing.Finally
the dynamic simulation results based on the monostatic and bistatic scattering coefficients of a cone-shaped model calculated via the FEKO software validate the proposed method.
