【摘要】：隨著現(xiàn)代裝備技術的日益發(fā)展,戰(zhàn)場上電磁干擾的形勢越來越嚴峻。為了與時俱進,適應現(xiàn)代戰(zhàn)場的復雜環(huán)境。現(xiàn)代雷達裝備必須在原來所具備的性能基礎上,切實提高抗干擾的能力,將理論轉(zhuǎn)化為工程實際,以適應實時戰(zhàn)場的需要。抗干擾能力是衡量雷達性能的主要標志之一,同時也作為整機系統(tǒng)設計的重要考慮。雷達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。本文主要針對有源干擾進行分析,列舉了多種主要的不同類型的干擾信號。雷達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。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)品能夠適應時代和戰(zhàn)場的需要。本文結合某中遠程三坐標雷達,以工程實踐為主要研究方法,完成了多種抗干擾技術的應用及實現(xiàn)。從工程實踐的角度對多種抗干擾技術進行討論。論文首先介紹了相控陣三坐標雷達的基本原理,系統(tǒng)基本組成及其抗干擾性能優(yōu)勢。詳細介紹了大動態(tài)接收機、數(shù)字脈壓、輔助通道、匿隱等技術的實現(xiàn)。深入分析和研究了天饋系統(tǒng)抗干擾技術的實現(xiàn)。以超外差接收機為基礎,在接收分系統(tǒng)中實現(xiàn)了多種抗干擾技術。聯(lián)合脈壓系統(tǒng)和信號處理系統(tǒng),進一步提高整機的抗干擾能力。利用多年來積累的工程實踐經(jīng)驗,充分發(fā)揮目前的工藝技術水平。根據(jù)各抗干擾措施的技術要求,對各相關的分系統(tǒng)進行硬件上改進,或者在原來的硬件基礎上增加一些硬件。在各抗干擾技術措施實現(xiàn)過程中,從整機的角度優(yōu)化好各分系統(tǒng),協(xié)調(diào)融合好各分系統(tǒng)。在原來的體制下采用了一些新的方法來實現(xiàn)技術指標。在多種抗干擾措施都實現(xiàn)以后,對多種抗干擾方法實現(xiàn)的效果進行分析。對部分抗干擾技術的實現(xiàn)效果采用仿真的方法介紹,部分技術采用錄取目標的效果來介紹�？垢蓴_措施在工程上實現(xiàn)以后要,通過調(diào)試發(fā)揮出硬件的最佳效能。最終研究結果表明,本文所應用的抗干擾方法達到了很好的效果,使雷達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.
