【摘要】：隨著現(xiàn)代裝備技術(shù)的日益發(fā)展,戰(zhàn)場(chǎng)上電磁干擾的形勢(shì)越來(lái)越嚴(yán)峻。為了與時(shí)俱進(jìn),適應(yīng)現(xiàn)代戰(zhàn)場(chǎng)的復(fù)雜環(huán)境�，F(xiàn)代雷達(dá)裝備必須在原來(lái)所具備的性能基礎(chǔ)上,切實(shí)提高抗干擾的能力,將理論轉(zhuǎn)化為工程實(shí)際,以適應(yīng)實(shí)時(shí)戰(zhàn)場(chǎng)的需要。抗干擾能力是衡量雷達(dá)性能的主要標(biāo)志之一,同時(shí)也作為整機(jī)系統(tǒng)設(shè)計(jì)的重要考慮。雷達(dá)面臨的干擾一般不是單一的干擾方式,而是多種干擾組成的綜合干擾。本文主要針對(duì)有源干擾進(jìn)行分析,列舉了多種主要的不同類(lèi)型的干擾信號(hào)。雷達(dá)的抗干擾也必須要采用具有多種抗干擾措施的綜合抗干擾技術(shù)。這樣,在同一部裝備上就擁有了較全面的抗干擾能力,使我們的產(chǎn)品能夠適應(yīng)時(shí)代和戰(zhàn)場(chǎng)的需要。本文結(jié)合某中遠(yuǎn)程三坐標(biāo)雷達(dá),以工程實(shí)踐為主要研究方法,完成了多種抗干擾技術(shù)的應(yīng)用及實(shí)現(xiàn)。從工程實(shí)踐的角度對(duì)多種抗干擾技術(shù)進(jìn)行討論。論文首先介紹了相控陣三坐標(biāo)雷達(dá)的基本原理,系統(tǒng)基本組成及其抗干擾性能優(yōu)勢(shì)。詳細(xì)介紹了大動(dòng)態(tài)接收機(jī)、數(shù)字脈壓、輔助通道、匿隱等技術(shù)的實(shí)現(xiàn)。深入分析和研究了天饋系統(tǒng)抗干擾技術(shù)的實(shí)現(xiàn)。以超外差接收機(jī)為基礎(chǔ),在接收分系統(tǒng)中實(shí)現(xiàn)了多種抗干擾技術(shù)。聯(lián)合脈壓系統(tǒng)和信號(hào)處理系統(tǒng),進(jìn)一步提高整機(jī)的抗干擾能力。利用多年來(lái)積累的工程實(shí)踐經(jīng)驗(yàn),充分發(fā)揮目前的工藝技術(shù)水平。根據(jù)各抗干擾措施的技術(shù)要求,對(duì)各相關(guān)的分系統(tǒng)進(jìn)行硬件上改進(jìn),或者在原來(lái)的硬件基礎(chǔ)上增加一些硬件。在各抗干擾技術(shù)措施實(shí)現(xiàn)過(guò)程中,從整機(jī)的角度優(yōu)化好各分系統(tǒng),協(xié)調(diào)融合好各分系統(tǒng)。在原來(lái)的體制下采用了一些新的方法來(lái)實(shí)現(xiàn)技術(shù)指標(biāo)。在多種抗干擾措施都實(shí)現(xiàn)以后,對(duì)多種抗干擾方法實(shí)現(xiàn)的效果進(jìn)行分析。對(duì)部分抗干擾技術(shù)的實(shí)現(xiàn)效果采用仿真的方法介紹,部分技術(shù)采用錄取目標(biāo)的效果來(lái)介紹�？垢蓴_措施在工程上實(shí)現(xiàn)以后要,通過(guò)調(diào)試發(fā)揮出硬件的最佳效能。最終研究結(jié)果表明,本文所應(yīng)用的抗干擾方法達(dá)到了很好的效果,使雷達(dá)的抗干擾性能得到了提高。
[Abstract]:With the development of modern technology and equipment, battlefield electromagnetic interference situation is more and more serious. In order to keep pace with the times, adapt to the complex environment of modern battlefield. Modern radar equipment must be in the original performance, and effectively improve the ability of anti interference, the theory into practice, in order to meet the needs of real-time battlefield interference. Ability is one of the main criteria for judging the radar performance, but also as an important consideration of the whole system design. The interference is generally not a single radar under jamming mode, but a variety of interference. This paper mainly consists of comprehensive interference for active interference analysis, enumerates several main different types of interference signals. The radar anti-jamming must also to adopt the comprehensive anti-jamming technology with a variety of anti-jamming measures. So, in the same department of equipment has a more comprehensive anti-jamming capability, so that Our products can meet the needs of the times and the battlefield. This combination of a remote three coordinate radar, the main research methods in engineering practice, the application and implementation of a variety of anti-jamming technology. To discuss a variety of anti-interference technology from the view of engineering practice. The paper firstly introduces the basic principle of phased array radar three coordinates. The basic composition and its anti-jamming performance advantages. Introduces dynamic receiver, digital pulse compression, auxiliary channel, realize the occult technology. In-depth analysis and study of the anti jamming technology of antenna system is realized. The super heterodyne receiver based on the receiving system achieve a variety of anti-jamming technologies combined with pulse compression system. And the signal processing system, further improve the anti-interference ability. The engineering practice experience accumulated over the years, give full play to the technological level at present. According to the For measures of anti-jamming technology, the hardware on the improvement of the related system, or add some hardware in the hardware based on the original. The anti interference technology measures in the process of implementation, optimization of each system from the angle of coordination fusion of every subsystem. Using some new methods in the original the system to achieve the technical index. After the anti interference measures are implemented in a variety of anti-interference methods, the effect was analyzed. The method to realize the effect of anti interference technology by simulation, the admission target technology to be introduced. The effect of anti interference measures in engineering later. Play the best performance through debugging hardware. The final results show that the anti-interference methods used in this paper to achieve good results, so that the anti jamming performance of radar has been improved.
