Abstract: The difference of the image generated by real target and Digital-Image-Synthesiser(DIS) is two
methods are deduced to recognize deceivable jamming generated by is the uncontinuity of the false target in cross
section(Doppler dimension) which is caused by the quantization of phase increment,and the other is the changing number
of the target in the imaging field after ISAR processing when the Pulse Repetition Frequency(PRF) of the DIS is un-
matched with the opposed radar’s the two methods,the limitations of DIS deceivable jamming are found,and the
false targets generated by DIS are effectively recognized.

摘要:分析了数字图像合成器(DIS)生成的目标图像与真实目标图像之间的异同点,经过推导,得出识别数字图像合成器欺骗
式干扰的方法:由于相位增量量化导致欺骗式假目标在横向多普勒方向上图像不连续;脉冲重复频率不匹配时,由 DIS 生成的欺
骗式假目标经 ISAR 处理后在成像视窗内目标数量会发生变化。从而发现了数字图像合成器欺骗式干扰的缺陷,对识别这种干
