Modeling and simulation of pulse compression radar based on an adaptive filter 基于自適應(yīng)濾波的雷達脈壓系統(tǒng)的建模與仿真
Moreover , the pulse compression radar has been widely used in practice because of its far detection range and good range resolution 此外,為了解決雷達作用距離和距離分辨力之間的矛盾,脈沖壓縮機技術(shù)在現(xiàn)代雷達系統(tǒng)中被廣泛采用。
Large time - band product signals such as linear frequency modulation signals ( lfm ) , nonlinear frequency modulation signals ( nlfm ) , phase coded signals and so on are one of key technologies for pulse compression radar systems 具有大時寬帶寬積的信號,如線性調(diào)頻信號、非線性調(diào)頻信號、相位編碼信號等是雷達應(yīng)用脈沖壓縮技術(shù)的關(guān)鍵之一。
In the first chapter the pulse doppler radar and pulse compression radar are introduced , include their definition , working condition and specialty . the method and theory of system simulation are discussed in chapter 2 . from the chapter 3 every module of the simulation is described 第一章主要對仿真中涉及到的脈沖多普勒( pd )雷達和脈沖壓縮( pc )雷達兩種雷達體制進行了簡述,給出了它們的定義,工作的環(huán)境,工作特點及各自的優(yōu)缺點。
Second , research and analyze the feature of signal of pulse compression radar , and discuss the principle and characteristic of pulse compression technique , that are linear frequency modulation and phase coding . the above two mathematic model is constructed , and shift - frequency noise is imposed on the models , and anti - nose ability is evaluated and simulated 通過對脈沖壓縮雷達的信號特征的研究和分析,通過研究線性調(diào)頻和相位編碼脈沖壓縮技術(shù)的原理和特點,建立了這兩種雷達的數(shù)學(xué)模型,并對此進行移頻干擾和相位編碼雷達干擾,并進行干擾性能的評估和仿真研究。
