【摘要】：隨著21世紀(jì)航運(yùn)業(yè)高速發(fā)展,雷達(dá)在水上航運(yùn)中的安全效能也越來越受到人們的重視。目標(biāo)檢測(cè)和跟蹤性能是影響雷達(dá)安全效能的兩項(xiàng)重要因素。雷達(dá)目標(biāo)檢測(cè)的主要任務(wù)是從噪聲、雜波干擾中發(fā)現(xiàn)目標(biāo),并提取目標(biāo)的各種有用信息,如角度、距離、速度等。雷達(dá)跟蹤的主要任務(wù)是估計(jì)和預(yù)測(cè)運(yùn)動(dòng)目標(biāo)下一時(shí)刻的狀態(tài)和確定目標(biāo)的軌跡。目標(biāo)檢測(cè)是跟蹤的前提,為了實(shí)現(xiàn)目標(biāo)的可靠性跟蹤,首先要保證對(duì)目標(biāo)的準(zhǔn)確性檢測(cè)。但是對(duì)于弱目標(biāo)而言,在海況復(fù)雜的雜波背景下不能有效的被檢測(cè)出來,這樣就無法保證對(duì)目標(biāo)的可靠跟蹤。因此,本文將檢測(cè)與跟蹤進(jìn)行綜合處理,以便提高弱目標(biāo)的檢測(cè)和跟蹤性能。 本文首先介紹了雷達(dá)目標(biāo)檢測(cè)與跟蹤的基本理論與方法,包括信號(hào)檢測(cè)的最佳準(zhǔn)則,恒虛警和脈沖積累檢測(cè)方法,卡爾曼濾波和機(jī)動(dòng)目標(biāo)跟蹤的方法,接著分析了檢測(cè)與跟蹤兩者之間的關(guān)系。 然后針對(duì)檢測(cè)前跟蹤算法與先檢測(cè)后跟蹤算法的不同,本文提出了一種判別機(jī)制,判斷何時(shí)啟用檢測(cè)前跟蹤算法。接著研究了針對(duì)弱目標(biāo)的動(dòng)態(tài)規(guī)劃?rùn)z測(cè)前跟蹤算法,并加入了兩級(jí)門限對(duì)其進(jìn)行了改進(jìn)。最后為了改變轉(zhuǎn)移步長(zhǎng),將卡爾曼濾波與動(dòng)態(tài)規(guī)劃進(jìn)行了結(jié)合,并進(jìn)行了仿真分析。 本文針對(duì)基于改進(jìn)的動(dòng)態(tài)規(guī)劃算法的檢測(cè)與跟蹤綜合處理算法,利用Visual Studio2010平臺(tái)進(jìn)行了軟件實(shí)現(xiàn)。為了加大處理速度,使用了基于CUDA的編程方法,并檢驗(yàn)了目標(biāo)檢測(cè)與跟蹤的效果。
[Abstract]:With the rapid development of shipping industry in 21th century. More and more attention has been paid to the safety effectiveness of radar in maritime navigation. Target detection and tracking performance are two important factors affecting radar security effectiveness. The main task of radar target detection is noise. In clutter, the target is found, and the useful information, such as angle and distance, is extracted. The main task of radar tracking is to estimate and predict the state of the moving target at the next moment and determine the track of the target. Target detection is the premise of tracking, in order to achieve the reliability of the target tracking. First of all, to ensure the accuracy of target detection. But for the weak target, can not be effectively detected in the sea complex clutter background, so it can not guarantee the reliable tracking of the target. In this paper, detection and tracking are integrated to improve the detection and tracking performance of weak targets. This paper first introduces the basic theories and methods of radar target detection and tracking, including the optimal signal detection criteria, CFAR and pulse accumulation detection methods, Kalman filtering and maneuvering target tracking methods. Then the relationship between detection and tracking is analyzed. Then, aiming at the difference between the pre-detection tracking algorithm and the pre-detection and post-tracking algorithm, a discriminant mechanism is proposed in this paper. Then the dynamic programming pre-detection tracking algorithm for weak targets is studied, and the two-level threshold is added to improve it. Finally, in order to change the transfer step size. The Kalman filter and dynamic programming are combined and simulated. In this paper, the integrated detection and tracking algorithm based on improved dynamic programming algorithm is implemented by using Visual Studio2010 platform. In order to increase the processing speed. The programming method based on CUDA is used, and the effect of target detection and tracking is verified.
