編隊(duì)衛(wèi)星SAR系統(tǒng)的模糊函數(shù)分析

Ambiguity Function of Formation Flying Satellites SAR System

  • 摘要: 從編隊(duì)衛(wèi)星SAR的特點(diǎn)出發(fā)，定義了編隊(duì)衛(wèi)星SAR的模糊函數(shù)，推導(dǎo)出了模糊函數(shù)的數(shù)學(xué)表達(dá)式，并進(jìn)行了計(jì)算機(jī)仿真。仿真結(jié)果充分驗(yàn)證了本函數(shù)的有效性。通過分析模糊函數(shù)可以直觀地看出編隊(duì)衛(wèi)星構(gòu)型對(duì)系統(tǒng)分辨率的影響，這為衛(wèi)星構(gòu)型的選擇提供了依據(jù)。
    Abstract: In this paper, the ambiguity function is defined and derived from the character of formation flying satellites SAR. The results of the computer simulations demonstrate the efficacy of the proposed function. Further, by analyzing the ambiguity function, it is clear to demonstrate the influence of satellites configuration on the system resolution, which provides principle for the selection of satellites configuration.
