| 中文摘要: |
| 声纳中具方向性的宽带强干扰严重影响远处舰船的检测。本文针对此问题,提出一种能实时抑制此类干扰的方法,它以保证干扰方向输出功率最小为约束条件,本文还研究了此方法对目标信号的性能影响情况。最后,通过对海试数据的处理,证明此方法在实践中比较有效。 |

| Directional wideband interference severely affects the detection of a faraway ship.In order to solve this problem,this paper presents a novel way which uses the criteria of minimum output power to cancel the directional wideband interference by real-time pro- cessing.The characteristic of the target signal affected by this method is also studied.Sea trial data is finally used to verify feasibility of the method,and the result is promising. |
