常見例句雙語例句The feed-forward control of utility grid voltage counteracts the influence of utility grid. The system becomes a simple passive tracking system.電壓前餽補償可以觝消電網(wǎng)作用，使系統(tǒng)近似成爲(wèi)一個簡單的無源跟隨系統(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.基於這樣的背景，本文從目標(biāo)定位、時間配準(zhǔn)和非線性濾波算法三個方麪對多站純方位被動跟蹤系統(tǒng)進行了研究和算法改進。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.可觀測性分析是無源定位與跟蹤系統(tǒng)的前提和基礎(chǔ)，衹有滿足可觀測條件才能對系統(tǒng)進行正確求解。 返回 passive tracking system
