【摘要】：隨著現(xiàn)代戰(zhàn)爭(zhēng)的發(fā)展,戰(zhàn)場(chǎng)環(huán)境的變化越來越復(fù)雜,這就對(duì)雷達(dá)系統(tǒng)的性能提出了越來越高的要求。同時(shí)雷達(dá)系統(tǒng)的設(shè)計(jì)變的越來越復(fù)雜,這就為雷達(dá)系統(tǒng)的調(diào)試帶來了很大的困難。為了能在較短的時(shí)間內(nèi)完成系統(tǒng)的調(diào)試、定型和批量生產(chǎn),若采用外場(chǎng)檢飛來對(duì)雷達(dá)系統(tǒng)進(jìn)行調(diào)試,成本高,調(diào)試周期長(zhǎng),無法滿足現(xiàn)在對(duì)雷達(dá)系統(tǒng)性能調(diào)試的需求;如果采用雷達(dá)信號(hào)模擬器對(duì)雷達(dá)系統(tǒng)進(jìn)行調(diào)試,則可有效的縮短調(diào)試周期,降低實(shí)驗(yàn)成本。所以雷達(dá)模擬器已經(jīng)成為雷達(dá)系統(tǒng)調(diào)試時(shí)不可或缺的重要設(shè)備。隨著現(xiàn)代計(jì)算機(jī)技術(shù)、大規(guī)模數(shù)字集成電路技術(shù)和雷達(dá)技術(shù)等相關(guān)領(lǐng)域的迅猛發(fā)展,現(xiàn)在的雷達(dá)模擬器已經(jīng)摒棄了單獨(dú)采用硬件或者軟件模擬的方法,現(xiàn)已廣泛采用軟、硬件相結(jié)合的形式,陣列雷達(dá)回波信號(hào)模擬器就是采用的此方法。而模擬器系統(tǒng)中的軟件部分是操作者和雷達(dá)信號(hào)模擬器系統(tǒng)人機(jī)交互的一個(gè)平臺(tái),是控制模擬器有效工作的核心,并且可以通過雷達(dá)信號(hào)模擬軟件模擬產(chǎn)生各種環(huán)境條件下的雷達(dá)回波信號(hào),為雷達(dá)系統(tǒng)調(diào)試提供一個(gè)可靠的數(shù)據(jù)來源。所以,軟件設(shè)計(jì)的好壞是雷達(dá)信號(hào)模擬器能否高效、快速工作的重要因素。本文主要以陣列雷達(dá)回波信號(hào)模擬器系統(tǒng)的研制為背景,詳細(xì)闡述了陣列雷達(dá)信號(hào)模擬器系統(tǒng)整體硬件和軟件的設(shè)計(jì)方案以及各部分要完成的功能,并對(duì)設(shè)計(jì)方案中的各部分功能進(jìn)行了詳細(xì)說明。在此基礎(chǔ)上,給出了雷達(dá)信號(hào)模擬器整體的數(shù)據(jù)流向和上位機(jī)界面應(yīng)用程序的設(shè)計(jì)流程,對(duì)系統(tǒng)上位機(jī)軟件的功能實(shí)現(xiàn)做了詳細(xì)的說明,并給出了調(diào)試問題的解決方法。最后,詳細(xì)說明了雷達(dá)回波信號(hào)的生成方法,主要是通過設(shè)置雷達(dá)信號(hào)模擬軟件中相應(yīng)的參數(shù),產(chǎn)生需要的多種雷達(dá)回波信號(hào)。由于該軟件只能產(chǎn)生單陣元的雷達(dá)信號(hào),所以,為了實(shí)現(xiàn)40陣元的回波信號(hào),文中以104?和85?平面陣為例,說明了波束形成的基本概念,以及各個(gè)陣元導(dǎo)向矢量的計(jì)算方法,給出了104?和85?平面陣的方向圖仿真結(jié)果,并對(duì)其做了簡(jiǎn)單分析。在此基礎(chǔ)上完成了整個(gè)系統(tǒng)軟件的設(shè)計(jì)和信號(hào)的產(chǎn)生,實(shí)現(xiàn)了系統(tǒng)各個(gè)部分的功能。
[Abstract]:With the development of modern warfare, the change of battlefield environment is becoming more and more complicated, which puts forward more and more requirements for the performance of radar system. At the same time, the design of radar system becomes more and more complicated, which brings great difficulties to the debugging of radar system. In order to complete the system debugging, setting and batch production in a short time, if the radar system is debugged by field inspection, the cost is high, the debugging period is long, and it can not meet the needs of the radar system performance debugging. If the radar signal simulator is used to debug the radar system, the debugging period can be shortened and the experiment cost can be reduced. Therefore, radar simulator has become an indispensable and important equipment in the debugging of radar system. With the rapid development of modern computer technology, large-scale digital integrated circuit technology, radar technology and other related fields, the current radar simulator has abandoned the use of hardware or software alone, and has been widely used in software. This method is adopted by array radar echo signal simulator in the form of hardware combination. The software part of the simulator system is a platform for man-machine interaction between the operator and the radar signal simulator system, which is the core of the effective work of the control simulator. The radar echo signal can be generated by the simulation software of radar signal under various environmental conditions, which provides a reliable data source for the debugging of radar system. Therefore, the quality of software design is an important factor for the high efficiency and fast operation of radar signal simulator. Based on the research and development of array radar echo signal simulator system, the whole hardware and software of array radar signal simulator system and the functions of each part are described in detail in this paper. The functions of each part of the design are explained in detail. On this basis, the design flow of the whole data flow direction and the upper computer interface application program of the radar signal simulator is given, the function realization of the upper computer software of the system is explained in detail, and the solution to the debugging problem is given. Finally, the generating method of radar echo signal is explained in detail, mainly by setting the corresponding parameters in radar signal simulation software to generate various radar echo signals needed. Because the software can only produce radar signal of single array element, so, in order to realize the echo signal of 40 array elements, in this paper, 104? And 85? The basic concept of beamforming and the calculation method of the guiding vectors of each element are illustrated for an example of plane array. And 85? The simulation results of the pattern of plane array are analyzed briefly. On this basis, the design of the whole system software and the signal generation are completed, and the functions of each part of the system are realized.
