The basics of lithography process, as well as the basic structure of lithographic system and the basic theory of partially coherent imaging are introduced in this paper. a bi - linear model of optical imaging is also presented. based on these theories, the simulation process of csplat is particularly analyzed, especially the computation of tccs ( transmission cross coefficient ) under different illuminations and the processing of primary lens aberrations inside tcc computation process
本文從光刻基本過程入手，介紹了光刻機光學系統的基本組成、部分相干光透射成像的基本原理，提出了光學系統的雙線性模型，並在此基礎上詳細分析了模擬軟體splat的模擬過程，其中著重分析了光學系統的傳輸交叉系數tcc的計算，包括不同照明系統下tcc的計算以及tcc計算中像差的處理。 -
It is widely used in both civil and military areas now. since sar and polarimetric sar is a coherent imaging system, its inherent speckle noise will produce important influence on the post - processing of sar images, such as target detection, classification and recognition, etc. so, speckle reduction becomes to the first step of sar images post - processing
由於sar和極化sar的相干成像特性，其固有的相干斑噪聲嚴重影響了后續目標檢測、分類和識別等應用，因此相干斑的抑製成為sar和極化sar圖像后處理的第一步，這種噪聲的抑制方法一直是極化sar信號處理領域一個很值得探討的問題。 -
As we all know, the capability of wireless communication system is constrained by radio propagation channel, especially for future wideband communication system. so it needs more signal processing techniques to withstand bad radio propagation environment, such as diversity combination, coherent detection and channel encoding and decoding etc. for mimo physical layer approaches, channel state information is a prerequisite, thus comes many channel estimation approaches and algorithms
無線通信系統的性能主要受到移動無線通道的制約，特別對未來的寬帶移動通信系統更需要採用很多信號處理技術來對抗惡劣的無線傳播環境以提高系統性能，比如常見的分集合併、相關檢測和通道編解碼技術等，而採用這些技術的前提就是要知道通道的狀態信息（ csi ） 。 -
Firstly, the theory and the architecture of hardware system are described, secondly, the steps of the signal processing are discussed in detail. based on the experiments and the characteristics of the signal, we pre - process the signals with band - pass filter, proportional amplifier and coherent demodulator. after sampling and analysis doppler information, we display the final results distinctly to alarm in time
然後，結合系統中各主要部分的任務，詳細介紹了信號處理的各個步驟：通過實驗比較，並結合接收信號的特點，選用帶通濾波器、比例放大器、相干檢波等技術對信號進行預處理；然後對獲得的多卜勒信息進行采樣和頻譜分析；最後，用比較直觀的形式顯示數據結果，以及時準確地告警。 -
