相位截距
英文
phase intercept-
Though the hill equation was improved it cannot satisfied with the long distance navigation. here is considering the main satellite the following satellite and the target satellite format a triangle in the space which was useful in the relative navigation. the orbit of the following satellite was resolved by calculate the hill equation
盡管如此改進的hill方程依然不能滿足遠距離的相對導航，當從星在攔截目標星時，若目標星在攔截過程中發生軌道機動遠離主星，這里考慮到在已知從星軌道的前提下利用主從星以及目標星在空間形成的三角關系這一有利條件進行幾何法定位的研究，並通過數學模擬對其誤差大小進行了分析。This paper gives a detailed account of the waveform, matched - filter, fuzzy function, resolution in speed, resolution in range and the capacity of anti - interference of the chirp signal. it deals with several methods to produce chirp signal and the advantages and disadvantages of these methods. it describes the working principle and performance of dds, analyses the phase errors initiated by the phase truncation and proposes a new scheme to solve the error
本文詳細介紹了以下幾個方面：線性調頻信號的波形、匹配濾波器、模糊函數、速度分辨力、距離分辨力及抗干擾能力；產生線性調頻信號的幾種方法並簡要分析了各種方法的優缺點； dds的工作原理、性能指標，分析了相位截斷產生的相位誤差，並提出解決這種誤差的新方案；設計了一個產生線性調頻信號的具體電路。The main achievement of the paper is to recommend the 90 point as the best place for sensor by the contrast of numerical calculation results and test signals. on the point the high frequency disturbing signal was weakened very much when the load impulse was changed, which could be explained when vibration shape was considered
本文最重要的工作是通過數值計算與實驗的對比確定點擊脈沖荷載作用下傳感器的最佳接收位置，即距離加載點相對于管樁截面中心夾角為90的點。
