| 中文摘要: |
| 噪声干扰器是一种压制性干扰器材,可用来对抗主被动声纳的搜索、跟踪。以压制后声纳的作用距离与压制前声纳的作用距离的比值为变化量,建立了噪声干扰器压制声纳的压制区域计算方法,定义了捷径曲线函数,并建立了捷径曲线函数和有效搜索宽度计算模型,通过计算压制前后有效搜索宽度的变化和噪声干扰器在不同位置有效搜索宽度的变化,可以对噪声干扰器压制声纳效果进行评价。 |
| 英文摘要: |
| Noise-jammer can be used to combat active and passive sonar search and tracking.In this paper,the ratio between the operating distances after and before the sonar being suppressed is used as a parameter to establish the model computing the suppression region created by noise-jammer.The shortcut curve function is defined,and the modle of computing the shortcut curve function and the effective search width is also set up.The effects of noise-jammer on suppressing sonar can be evaluated by computing the effective search widths before and after suppression and the variation of the noise-jammer’s effective search width at different position. |
