摘　　要：首先利用电磁散射理论分析了空中目标在超宽带(UWB)雷达照射下的电磁散射特性,阐述了UWB雷达目标识别的方法与步骤,然后对回波信号的相参积累用于提高UWB雷达目标识别概率的效果进行了分析。理论分析和计算机仿真结果均表明,在低信噪比的情况下,相参积累方法可以提高UWB雷达的目标识别概率。At first,the electromagnetic scatter feature of targets irradiated by UWB radar is analyzed by using the theory of electromagnetic scatter. The methods and approaches of UWB radar target recognition are expatiated. Then,the effect of improving UWB radar target recognition probability by echo coherent accumulation is analyzed. Theoretical analysis and the results of simulation show that coherent accumulation can improve UWB radar target recognition probability in the condition of low signal noise ratio.
