中文拼音 [xiāngwèitīxíng]
相位梯形
英文
phase keystone-
Take integrity of object information into condition, a two - dimension signal processing method which can make a measurement of the target ’ s speed as well as the range is brought forward at the basis of waveform parameter design. and simulation in the background of hf multi - object with noise is taken. a comparison of signal properties, processing and antinoise detection performance is taken between mcpc and another two high range resolution radar signals : single carrier pulse coded signal and step frequency pulse coded signal
考慮到目標信息提取的相對完整性，以高頻雷達為背景，在對多載波相位編碼脈沖串信號參數設計的基礎上，推導了三種多載頻相位編碼脈沖串信號的距離速度二維處理過程並相應的對多目標噪聲環境進行了模擬;將多載波相位編碼信號與另外兩種距離高分辨信號:單載頻相位編碼信號和相位編碼階梯跳頻信號，在信號特性、處理過程和抗噪聲特性方面進行了對比;本文從理論上為多載波相位編碼信號的波形設計和分析、信號的處理打下基礎。Firstly, the principle of phase gradient autofocus and rank one phase estimate and its advanced are detailed. secondly, it proposes an algorithm of fast maximum contrast phase compensation after discussing its similar algorithm fast minimum entropy phase compensation
討論了經典的相位梯度自聚焦演算法、秩一相位誤差演算法及其改進形式;在討論快速最小熵相位補償演算法的基礎上，提出了對比度最優相位調整演算法，實測數據處理表明了該演算法的有效性。To bj1027 pick up, for former - brind " generally great change augmenting tyre " landscape - orientation - mete, then result tyre leaning - grind. through plentiful market researching, correlative examination, data stat analyse, theory calculating and the same products and car comparating, we make clear the relation and the movement connection in suspend, veer and tyre, confirm again veer trapezia - cut - point, and adopt a series of measures, resovle tyre leaning - grind completely, elevate the whole track " capability
我們通過大量的市場調查、相關的檢測與試驗、數據的統計分析、理論分析計算，並對比同類產品及轎車進行分析研究，弄清了懸架、轉向與輪胎之間的相互聯系與運動關系，重新確定了轉向梯形斷開點的位置，並相應採取了一系列措施，徹底解決了輪胎偏磨這一問題，使整車性能得到了明顯提高。
