常見例句雙語(yǔ)例句The feed-forward control of utility grid voltage counteracts the influence of utility grid. The system becomes a simple passive tracking system.電壓前饋補(bǔ)償可以抵消電網(wǎng)作用，使系統(tǒng)近似成為一個(gè)簡(jiǎn)單的無(wú)源跟隨系統(tǒng)。According to this, this paper focuses on the study of bearings-only passive tracking system in the aspects of the target location, time alignment and nonlinear filtering algorithm.基于這樣的背景，本文從目標(biāo)定位、時(shí)間配準(zhǔn)和非線性濾波算法三個(gè)方面對(duì)多站純方位被動(dòng)跟蹤系統(tǒng)進(jìn)行了研究和算法改進(jìn)。Observability analysis is the basic and prime task in passive localization and tracking system, for only when the system is observable, it can be determined with unique and definite solution.可觀測(cè)性分析是無(wú)源定位與跟蹤系統(tǒng)的前提和基礎(chǔ)，只有滿足可觀測(cè)條件才能對(duì)系統(tǒng)進(jìn)行正確求解。 返回 passive tracking system
