STUDY OF TWO-DIMENSION STRUCTURE IMAGE METHOD OF RADAR TARGET

该文首先研究了雷达目标二维电磁散射的频域散射模型;而后提出了用参数估计方法实现目标ISAR成像的思想,并研究了MP2D参数估计方法;最后用仿真数据和波音727客机真实目标实测数据对该方法进行了实验验证。实验结果表明,该方法能准确估计目标的二维散射中心,且对噪声有较强的抑制能力。

In this paper, first, the frequency scatter model of radar target two-dimension electromagnetic scattering is studied, then, the idea of ISAR by parameter estimation method is presented and the MP2D method is researched, finally, the experimental result is given using simulated data and measured data of Boeing 727 airplane and demonstrated that this method could accurately extract two-dimension scattering center of radar target and is low sensitive to noise.
