【摘要】：隨著雷達(dá)以及各種高新技術(shù)的發(fā)展,雷達(dá)在國防、航天、軍事、通信等各方面的應(yīng)用越來越普及。但是雷達(dá)的功能越來越復(fù)雜,也使得雷達(dá)設(shè)備的測(cè)試和驗(yàn)證很不方便,雷達(dá)回波模擬技術(shù)應(yīng)運(yùn)而生。雷達(dá)回波模擬器擁有很多得天獨(dú)厚的優(yōu)勢(shì),方便、靈活、經(jīng)濟(jì),還能重復(fù)應(yīng)用,很多雷達(dá)研究機(jī)構(gòu)都將其作為一種必要的工具來研制雷達(dá)。本文以專用于機(jī)載雷達(dá)測(cè)試的XX雷達(dá)回波模擬器項(xiàng)目為背景,從理論出發(fā),首先研究了雷達(dá)目標(biāo)基本特性,然后結(jié)合項(xiàng)目需求,建立了回波和干擾信號(hào)基本模型,重點(diǎn)討論了欺騙干擾的幾種拖引方式,最后對(duì)整個(gè)項(xiàng)目的系統(tǒng)組成進(jìn)行了分析,設(shè)計(jì)并實(shí)現(xiàn)了一套完整的系統(tǒng)控制軟件,并給出了整個(gè)系統(tǒng)的調(diào)試結(jié)果。XX雷達(dá)回波模擬器功能強(qiáng)大,可以同時(shí)產(chǎn)生目標(biāo)、雜波、以及不同干擾所引起的回波。其控制軟件可以對(duì)模擬器的每個(gè)功能單獨(dú)控制,也能統(tǒng)一分配任務(wù),所以其結(jié)構(gòu)也非常復(fù)雜。本文采用模塊化思想對(duì)控制軟件進(jìn)行設(shè)計(jì),對(duì)每一個(gè)模塊的細(xì)節(jié)都展開了深入的討論,包括需求分析、結(jié)構(gòu)設(shè)計(jì)與最后的實(shí)現(xiàn)。然后給出了每個(gè)模塊的軟件流程圖,并采用UML圖來詳細(xì)解釋每個(gè)模塊的內(nèi)部結(jié)構(gòu)以及某些模塊之間的層次關(guān)系。本文研究的控制軟件嚴(yán)格按照面向?qū)ο缶幊痰能浖O(shè)計(jì)思想,結(jié)合設(shè)計(jì)模式和三層架構(gòu)的層次結(jié)構(gòu),遵循“高內(nèi)聚,低耦合”的原理,讓整個(gè)軟件系統(tǒng)更加模塊化,系統(tǒng)化,也更加方便了系統(tǒng)的升級(jí)與優(yōu)化。采用多線程編程與異步通信的原理,實(shí)現(xiàn)不同模塊之間的數(shù)據(jù)傳輸。
[Abstract]:With the development of radar and all kinds of high-tech, radar is more and more popular in national defense, spaceflight, military, communication and so on. However, the function of radar is becoming more and more complex, which makes the testing and verification of radar equipment very inconvenient, and radar echo simulation technology emerges as the times require. Radar echo simulator has many advantages, such as convenience, flexibility, economy and repeatability. Many radar research institutions use it as a necessary tool to develop radar. In this paper, based on the project of XX Radar Echo Simulator, which is specially used for airborne radar testing, the basic characteristics of radar target are studied firstly, and then the basic model of echo and jamming signal is established according to the requirements of the project. Several towing methods of deception interference are discussed emphatically. Finally, the system composition of the whole project is analyzed, and a complete system control software is designed and implemented. The debugging result of the whole system is given. Xx radar echo simulator is powerful, which can produce the target, clutter and echo caused by different jamming at the same time. Its control software can control each function of simulator separately and assign tasks uniformly, so its structure is very complex. In this paper, the modularization idea is used to design the control software. The details of each module are discussed in depth, including requirement analysis, structure design and final implementation. Then the software flow chart of each module is given, and the UML diagram is used to explain the internal structure of each module and the hierarchical relationship between some modules in detail. The control software studied in this paper is strictly in accordance with the software design idea of object-oriented programming, combines the design pattern and the hierarchical structure of three layers, and follows the principle of "high cohesion and low coupling", which makes the whole software system more modular and systematic. Also more convenient system upgrade and optimization. The principle of multithread programming and asynchronous communication is adopted to realize data transmission between different modules.
