| 摘 要： | 以锥体目标为研究对象,建立了双基地雷达进动目标宽带回波模型,提出了基于两个接收站观测的1维距离像序列和扩展Hough变换的进动参数联合估计方法;建立了进动目标双基地ISAR成像模型,推导了双基地IS-AR成像最佳时间,并通过前述参数估计结果选择对应的1维距离像,采用FFT实现横向压缩获得了进动目标双基地ISAR像;采用FEKO软件计算了一个锥体模型的单/双基地散射系数并进行动态仿真,仿真结果验证了本文方法的有效性.

| Abstract: | 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. |
