受限于便携性要求，超宽带穿墙成像雷达可用的天线数量有限，因而面临着如何充分利用有限的天线获取最优成像性能的难题。文中主要比对研究了UWB、 TWIR在3种不同天线阵列配置模式下的性能。论述了3种不同的阵列配置模式，分析比对了在3种模式下UWB、 TWIR的方位向分辨率和干涉区域，并通过仿真实验进行了验证分析，给出了合理等效孔径和虚拟阵元密度下的最佳阵列性能配置参考。

Considering the requirement of portability , the number of antennas used for the portable ultra-wide-band ( UWB) through wall imaging radar ( TWIR) is limited.It is faced with challenges to take full advantage of an-tennas to obtain the optimal performance.In this paper , we study three kinds of array configuration modes and com-pare their imaging performance based on two criterions-cross-range resolution and interference region ( IR).Our simu-lation results show that the array configuration should be considered carefully to get the optimized aperture and ele -ment density.
