| 摘 要： | 在双基地ISAR成像模型的基础上,通过解线频调处理得出双基ISAR回波信号的差频域表示,针对参考信号跟踪存在误差而影响成像质量的问题,采用距离对准消除跟踪误差的影响;而后采用单特显点法补偿由于距离对准而产生的初相误差,最终给出了整个双基ISAR成像算法流程,最后通过对点目标模型的仿真,验证了该算法的有效性。

| Abstract: | Based on bistaitc ISAR imaging model,the paper elicits expression of echo signal of bistatic ISAR by demodulation of liner frequency.With regard to inaccuracy of track of reference signal to effect the quality of imaging,this paper introduces range alignment to compensate inaccuracy of track and then adopts the method of single power scatter point to compensate inaccuracy of phase.At last,the flow of bistatic ISAR imaging algorithm is shown.Finally,some simulation results are given to prove the validity of the algorithm in this paper. |
