摘　　要：由于冲激雷达回波信号中无法提取出多普勒频率信息,传统的基于频域成像的方法不再适用于冲激雷达成像系统。近年来,基于冲激雷达的成像算法研究引起了较多关注,对冲激雷达成像算法进行综述。首先简单介绍了冲激雷达的定义,然后总结归纳了3类基于冲激雷达的成像方法,详细阐述了各种算法的原理,指出了各种成像算法中的优点和不足,最后阐述了有待进一步研究的方向。Since the Doppler frequency cannot be extracted from echo signals of the impulse radar,the traditional imaging method is no longer applicable to the impulse radar imaging system in the frequency domain.In recent years,imaging algorithms based on impulse radars attract more and more attention and these algorithms are reviewed.The definition of the impulse radars are briefly described.Three classes of imaging algorithms based on impulse radars are summarized,the principles of these algorithms are elaborated and the advantages and disadvantages of them are pointed out.Finally,the trend of impulse radar imaging is forecasted.
