【摘要】：近年來,我國的經(jīng)濟實力與日俱增,電子信息產(chǎn)業(yè)與航運業(yè)蓬勃發(fā)展,船用導(dǎo)航雷達的市場需求更為廣闊。然而民用導(dǎo)航雷達多被國外公司壟斷,國內(nèi)企業(yè)在該領(lǐng)域起點低、起步晚,故研制具有自主知識產(chǎn)權(quán)的導(dǎo)航雷達有著極高的市場價值和戰(zhàn)略意義。本文研究了雷達數(shù)據(jù)處理技術(shù),并結(jié)合實際雷達系統(tǒng)研制了顯控軟件,通過仿真驗證了其實用性。首先,對于雷達數(shù)據(jù)處理過程中的點跡處理技術(shù)進行分析研究。分析了本文采用的固態(tài)源發(fā)射機體制的雷達形成多值性的原因,研究了為獲得點跡唯一估計值的凝聚處理方法�？紤]到目標(biāo)在運動平臺下參考系的使用不同,分析了常見參考系的轉(zhuǎn)換方法。然后,研究了雷達數(shù)據(jù)處理過程中對于航跡處理的算法。其中,航跡起始主要研究了直觀法和M/N邏輯法,在邏輯法的基礎(chǔ)上通過對波門的控制進行優(yōu)化改進,減少虛假航跡。仿真各個起始算法,驗證改進航跡起始算法的良好性能。最近鄰域標(biāo)準(zhǔn)濾波(NNSF)和概率數(shù)據(jù)互聯(lián)濾波(PDAF)是工程上常用的點跡-航跡關(guān)聯(lián)算法,仿真對比了兩種算法,驗證了在雜波環(huán)境中使用PDAF算法的效果更好。研究了聯(lián)合概率數(shù)據(jù)關(guān)聯(lián)濾波(JPDAF)以解決上述濾波算法在多目標(biāo)交叉運動的情況下跟蹤精度較低的問題。由于JPDAF算法復(fù)雜實現(xiàn)困難,在此基礎(chǔ)上研究了經(jīng)驗JPDAF。通過仿真驗證了JPDAF對比PDAF的優(yōu)勢和經(jīng)驗JPDAF的有效性和可行性。航跡濾波在卡爾曼濾波的基礎(chǔ)上,研究了一階擴展卡爾曼濾波(EKF)和轉(zhuǎn)換量測卡爾曼濾波(CMKF),仿真驗證了CMKF在非線性較強的情況下效果更好。最后,完成在通用計算機上雷達顯控軟件設(shè)計與實現(xiàn)。該軟件包括通信模塊、雷達數(shù)據(jù)處理模塊、雷達視頻顯示模塊以及以電子海圖為顯示背景的態(tài)勢顯示模塊。其中,前面雷達數(shù)據(jù)處理技術(shù)研究的為雷達數(shù)據(jù)處理模塊的基礎(chǔ)。該軟件系統(tǒng)可以實現(xiàn)對雷達的操作以及顯示雷達工作狀態(tài)、回波信息,且提供雷達數(shù)據(jù)處理功能,實現(xiàn)對雷達數(shù)據(jù)的處理,形成航跡。論文通過仿真產(chǎn)生多目標(biāo)交叉運動,測試了該軟件雷達數(shù)據(jù)處理的實用性和有效性。
[Abstract]:In recent years, the economic strength of our country is increasing day by day, the electronic information industry and shipping industry develop vigorously, the market demand of marine navigation radar is wider. However, most of the civil navigation radar is monopolized by foreign companies, and domestic enterprises have low starting point and late start in this field, so it is of high market value and strategic significance to develop navigation radar with independent intellectual property rights. In this paper, the radar data processing technology is studied, and the display and control software is developed in combination with the actual radar system. The practicability of the software is verified by simulation. Firstly, the point trace processing technology in radar data processing is analyzed and studied. In this paper, the reason why the radar of the solid-state source transmitter system is multi-valued is analyzed, and the coacervation processing method for obtaining the unique estimation of the point trace is studied. Considering the different use of reference system under moving platform, the conversion method of common reference system is analyzed. Then, the algorithm of track processing in radar data processing is studied. Among them, the path initiation mainly studies the intuitive method and the M / N logic method. On the basis of the logic method, the control of the wave gate is optimized and improved to reduce the false track. The simulation results show that the improved track initiation algorithm has good performance. Recently, the neighborhood standard filter (NNSF) and probabilistic data interconnect filter (PDAF) are commonly used in engineering. The simulation results show that the PDAF algorithm is more effective in clutter environment. The joint probabilistic data association filtering (JPDAF) is studied to solve the problem that the tracking accuracy of the above filtering algorithm is low in the case of multi-target cross motion. Because the JPDAF algorithm is difficult to implement, the empirical JPDAF is studied. The effectiveness and feasibility of JPDAF compared with PDAF and empirical JPDAF are verified by simulation. Based on the Kalman filter, the first order extended Kalman filter (EKF) and the converted measurement Kalman filter (CMKF) are studied. The simulation results show that CMKF is more effective in the case of strong nonlinearity. Finally, the design and implementation of radar display control software on general computer are completed. The software includes communication module, radar data processing module, radar video display module and situation display module based on electronic chart. Among them, the research of radar data processing technology is the basis of radar data processing module. The software system can realize the operation of radar, display the working state of radar, echo information, provide the function of radar data processing, realize the processing of radar data and form track. This paper tests the practicability and validity of the software radar data processing by simulating multi-target cross motion.
