摘　　要：利用多雷达回波信号对目标进行融合成像可以有效提高分辨率。本文实现了一种多雷达融合联合超分辨成像算法,该方法基于单雷达观测数据指数和模型,建立了联合的多雷达观测数据模型,并将雷达二维成像的矩阵束算法引入到多雷达观测融合成像中,利用多雷达观测数据估计散射中心的参数,有效提高了分辨率。仿真实验表明,该算法有效提高了雷达成像的分辨性能,有利于后续的目标检测与识别。Combining muhi-radar echoes could obviously improve the radar imaging resolution. This paper implemented a multi - radar united super-resolution imaging algorithm. Based on the exponential model of single radar echoes, the united multi-radar data model was founded firstly. Then we introduced the matrix pencil algorithm into the multi-radar fusion imaging, and estimated the parameters of the scattering centers. Monte-Carlo simulations demonstrated that the algorithm could effectively improve the performance of radar imaging which is favorable to the target detection and identification.
