現有的艦載兩軸雷達由於受到船搖的影響,不僅波束傾斜,而且天頂附近有很大的跟蹤盲區。A radar beam picks out the moving target and stays with it all the time.
雷達波束能辨認出活動的目標,並一直跟蹤該目標。Parabolic antenna in a widely used is tracking antenna area, by use the optimum design, it may produce a very narrow beam, it ' s tracking precision is high, but because it ' s beam width is very narrow, the searching target is very difficult
摘要拋物面天線是火控雷達中普遍使用的一種跟蹤天線,通過系統優化設計,可以形成很窄的波束,所以其跟蹤精度很高,因為其波束很窄,所以搜索發現目標困難。And the results of them have been analyzed, from basic one to sum - difference beam measurements which are popular in phased array radar. then there is a deep investigation on the application of sum - difference amplitude comparison in target tracking in the multi - path environment. finally, the origin of multi - path effects is analyzed and some methods to eliminate the multi - path effects are introduced briefly
從基本的方法入手,過渡到相控陣雷達常用的單脈沖和差波束法,分析了這些方法各自的測角效果;著重研究了多徑效應影響下比幅和差波束法在目標跟蹤中的運用,並分析了多徑效應的形成原因,簡單介紹了幾種常用的多徑消除技術。It is proved by computer simulation that the slant 3 - axes radar can be used in target tracking in the whole air space without blind zone and beam slant. it is pointed out that the slant 3 - axes radar can reduce the maximum angle for elevation axis compared with 3 - axes perpendicular radar, then reduce the technique demand of angular velocity and acceleration of elevation axis
通過模擬驗證了傾斜三軸雷達系統在工程上可以做到波束無傾斜和全空域跟蹤無盲區的結論,並指出此系統與正交三軸系統相比,可以減少俯仰軸的最大轉動角,從而降低系統對俯仰軸的角速度和角加速度的技術要求。分享友人
