  1. Presents the development of modern signal processing techniques, a new implementation method which realizes quadrature coherent detection by direct sampling of if signal generated during the implementation of traditional quadrature coherent detection with analog elements in the form of two parallel baseband channels where in phase ( i ) and quadrature ( q ) components of ceived if singnal where, the imperfect matching of the separate channels due to the analog elements results in high phase and amplitude which meets the needs for high performance radar signal processing, the elementary principles and the implementation process for each method and concludes from simulation results to compare their features and application conditions that the new approach can satisfy of the requirements of high performance sp

    針對近年來提出的通過直接中頻采樣來實現正交相干檢波的方法，分析了其基本實現原理，並用統一的觀點解釋了迄今為止國內外基於此提出的各種實現方法；對每一實現方法的基本原理和實現過程都作了分析，並給出了計算機模擬結果；在此基礎上比較了各方法的性能指標及適應條件.理論分析和模擬結果證明，這一方法完全可以滿足高性能信號處理的要求
  2. Ground penetrating radar or georadar, is a new no destroying detection instrument with rapidly developing in recent years. it is applied to engineering, environment, archaeology and other aspects. data processing ' s theories and methods are one of the key aspects in gpr researching, because these are useful to picking up parameters in reflection wave including amplitude, phase, frequency and so on

    數據處理（包括濾波、反褶積、偏移等）是gpr的研究重點之一，其目的是壓制隨機的不規則的干擾波，以最大可能的解析度在探地雷達剖面上顯示反射波，提取反射波的各種有用參數（振幅、相位、頻率等）來幫助解釋。
  3. A coherent electromagnetic pulse in the range between the far - infrared and microwave region is used as a detection source. the amplitude of the wave is recorded by electro - optical or photoconductive sampling. after fast fourier transform, the amplitude and phase of the wave is given, then the complex refractive index standing for the absorption and dispersion of the material in thz region is extracted

    Thz （ 10 ~ （ 12 ） hz ）時域光譜技術是20世紀90年代發展起來的一種新型的光譜測量技術，它使用頻率介於遠紅外和微波之間的相干電磁輻射脈沖作為探測源，利用電光取樣或光電導取樣的方法直接記錄thz輻射電場的振幅時間波形，通過傅立葉變換得到測量信號振幅和相位的光譜分佈，進而獲得材料在thz波段的復介電常數，即色散及吸收等信息。
