  1. Second, this paper analyzes the time - frequency distribution of the clutter from airborne pulse doppler radar ( pdr ). the side - lobe clutter, which is the main factor to influence the pdr, is analyzed and calculated. based on the simulation of typical geometry of the land, we analyze and discuss the side - lobe clutter and concluded that the dft of can be considered as the phase of the coho

    並且根據各種典型地貌的近似模擬，從統計特性上和頻率域上對脈沖多卜勒雷達的旁瓣雜波進行了分析討淪，還得出脈沖多卜勒雷達的dft可以近似地看作相參積累，並在程序的編制中利用了這一個結論。
  2. The main research works of this dissertation are aimed to design of radar waveform and the application of wavelets in ultra - wide radar, including : the design of a new kind of hybrid radar and the research of time side - lobe suppression for pulse compression, the design of receiver r adio front end in data acquisition of ultra - wide band radar, the time delay estimation based on wavelets ( packet ) analysis

    本文主要進行雷達波形設計研究以及研究小波理論在超寬帶雷達中的應用，集中體現在以下幾個方面：一類新的組合雷達波形設計及壓縮脈沖時間旁瓣抑制技術研究、超寬帶雷達多通道數據採集方法中前端射頻接收部分的設計及研製、基於小波（包）方法的時延估計方法。
  3. 2 in the research of time side - lobe suppression for pulse compression, a method designing mismatch network according to the desire waveform of compression pulse is proposed
