| 摘 要： | 角反射器干扰是舰船应对反舰导弹的一种重要无源干扰形式,为了提高反舰导弹的作战效能,利用目标宽带条件下极化分解比重邻频差异的统计特性,将Krogager极化分解算法用于舰船和角反射器阵列的鉴别。该算法采用双门限的设定,不仅可以判别待识别模式极化分解在频率上的稳定性,而且可以进一步判别在姿态上的稳定性。结果表明角反射器阵列的极化分解比重不仅随频率变化具有稳定性,并且随角反射器个数的变化也具有稳定性,而舰船的极化分解比重随频率的变化具有敏感性,达到较好的鉴别效果。 |

| Abstract: | The jamming of corner reflector is a very important form of passive jamming which is used to be against the anti-fleet missile on naval vessels.In order to improve the performance of anti-fleet missiles,the statistical characteristics of the difference between neighboring frequencies in the proportion of Krogager polarization decomposition is used to distinguish the naval vessels from the corner reflector array in the condition of broad band.The algorithm,which adopts enactment of double threshold,not only ... |
| Keywords: | anti-jamming of corner reflector polarization decomposition algorithm double threshold discrimination of polarization |
