Due to restriction with the array aperture transition time, traditional phased array radar works under relative narrow signal bandwidth, so this restricts the application of phased array radar in the field where high performance is demanded. however, optically controlled phased array radar ( ocpar ) adopts the photoelectron technology, counteracts the aperture transition time via the method of optical true time delay ( ottd ), so it can realize wide instantaneous bandwidth and squint - free operation ; meanwhile, it can realize the miniaturization of phased array radar and has super anti - electromagnetism interference capability
而光控相控陣雷達採用光電子技術,通過光實時延遲的方法來抵消孔徑渡越時間,可以實現相控陣雷達的寬帶寬角掃描;同時也可以使得相控陣雷達小型化,並具有強的抗電磁干擾的能力;另外,由於光纖傳輸具有損耗低、頻帶寬等固有優點,採用光纖連接雷達天線和雷達控制中心,可以使兩者的距離較採用同軸電纜有較大的提高,更有利於保護雷達控制中心。Some functional blocks are set up with the basic block provided by spw, and some is programmed with c language. after the simulation of pulse compress mtd radar, the effect of some jamming signals is analyzed. especially, the jamming signal of high pulse repeat frequency is discussed
完成脈沖壓縮mtd雷達的建模以後,又討論分析了幾種常見的干擾式樣,如噪聲調幅干擾、噪聲調頻干擾等,著重討論了高重頻噪聲調頻脈沖信號的干擾效果,並對幾種不同形式信號的干擾效果進行了比較和分析。Then on one hand, author makes researches of anti - jamming against pulse jamming 、 gauss white noise jamming and radio frequency noise jamming from the side of signal processing. author exercises much signal processing knowledge of time - domain sliding window accumulation 、 wavelet analysis 、 time - frequency analysis and linear prediction and carries out many simulation experiments. on the other hand, author proposes the anti - jamming methods of using a sar similar to double - base radar and modulating the amplitude 、 the phase of emission signal and changing the frequency modulation slope from the side of changing sar system model
作者首先提出了合成孔徑雷達抗干擾的定義、分類以及評價抗干擾方法好壞的主客觀標準;然後,一方面從信號處理的角度出發對脈沖式干擾、高斯白噪聲干擾以及射頻噪聲干擾進行了抗干擾研究,其中運用了時域滑動窗口積累,小波分析,時頻分析以及線性預測等信號處理知識,做了大量的模擬實驗;另一方面,本文基於改變合成孔徑雷達系統模式提出了利用類似雙基地雷達來抗干擾,以及對發射信號進行調幅、調相以及改變調頻斜率來抗干擾,同樣做了相應的模擬實驗。The subdivision algorithm will be listed in chapter 4 section 3. 4 } generation of radar interfrence image and target swap simulation improve the simulation of radar / arpa simulator
