Chapter 4 proposes two false target jamming detection schemes by dual - aperture antenna along - track and cross - track interferometric sar, which are based on moving target detection technique and spatial cancellation algorithm
第四章將動目標檢測技術和空域對消技術引入到對干擾目標的檢測中,提出了沿航跡和跨航跡雙天線干涉對消檢測虛假圖像欺騙干擾的方法。First, this paper expatiates on the theory about the apparatus of determining object ' s coordinate. in order to get the place and data of the moving object, the track ' s data arc selected from the images and are dealt with several methods. second, the paper discusses a new method that is based on the technology of fuzzy math ' s image intercepting
本文對目標坐標測定儀所依賴的原理進行了理論闡述,為了得到空中運動目標的位置和運動參數,對于每一周期所採集的圖像進行了實時的處理,包括濾波、二值化、目標圖像分割及各種參數提取,這是目標航跡建立所必須的,其成果也已經應用於坐標測定儀中。Then its mathematical model is set up and its validity is proved by computer simulation results. in the following, a new processing method of using three - antenna to detect, locate and image moving target is proposed based on dpca and interferometric theory. this method can not only suppress ground clutter effectively and detect moving target but also locate accurately azimuth position of moving target and estimate its velocity
深入分析了dpca和干涉的原理后,提出一種沿航跡放置的三天線sar動目標檢測和成像方法,詳細描述了該方法的工作機理,給出系統組成框圖,並給出該方法進行動目標檢測、定位、測速和成像的步驟,然後給出了計算機模擬方案及大量的模擬結果,充分證明了採用該方法不僅能夠有效的抑制地雜波、檢測動目標,還能夠對動目標精確定位,準確估計出動目標的速度,對動目標重新聚焦成像。The same target will appear two courses on the electronic chart for the errors of the two sensors are statistically independent. the paper mainly includes two points : ( 1 ) study the fusion between ais data and radar data in vts ; first the paper discusses the kalman filter of the target ' s tracking. on the basis of which we study the data fusion between the track of radar target and that of ais target
對于雷達目標的航跡,選擇雷達作為位置傳感器,對于ais目標,選擇gps (全球定位系統)接收機作為位置傳感器,由於測量雷達航跡和ais航跡的傳感器是不同的,兩種傳感器誤差是相互獨立的,這樣在海圖上顯示目標的時候出現對于同一目標出現不同的航跡,本研究的重點包括兩個方面: ( 1 )研究vts系統中ais數據和雷達數據的融合:首先討論目標航跡的kalman濾波,在目標航跡kalman濾波的基礎上對雷達目標和ais目標的航跡進行數據融合的研究;同時本研究將對ais的位置傳感器分差分gps和非差分gps兩種情況進行分析和處理。Space - borne radar parameters are used in simulation. base on the doppler frequency of rebound jamming signal, along - track interferometric detection scheme, which is proposed in chapter 4, is employed to detect point target rebound jamming in simulation, and the results validate the feasibility of this kind detection scheme. at last, a detailed comparison between rebound jamming and false target jamming is made
第五章介紹了彈射式干擾原理,對干擾信號特徵及干擾效果作了具體的分析,並利用機載sar參數作了干擾模擬實驗;根據彈射式干擾信號多普勒頻率的特點,利用沿航跡雙天線干涉對消技術對彈射式點目標干擾進行檢測,分析了模擬結果;最後還將彈射式干擾與虛假圖像干擾進行了比較。分享友人
