【摘要】：隨著雷達技術(shù)的不斷發(fā)展,當(dāng)今戰(zhàn)場上的信號環(huán)境,被多種參數(shù)和多種制式的雷達輻射信號相互交叉影響著,從而對位于戰(zhàn)場內(nèi)的雷達偵察設(shè)備也提出更高的性能要求。在新的雷達偵察設(shè)備研制過程中,為準確測試偵察設(shè)備的定位性能,需要為其提供一個較為真實的戰(zhàn)場信號群環(huán)境作為實驗基礎(chǔ)。但是利用真實的輻射源設(shè)備來重構(gòu)信號環(huán)境的做法,受到外界氣候、實驗場地和實驗經(jīng)費等多種因素的影響而變得不切實際。因此,開發(fā)一款能夠應(yīng)對這一難題的仿真軟件來還原真實的戰(zhàn)場信號群環(huán)境,具有重要的意義和價值。本課題基于復(fù)雜信號環(huán)境的動態(tài)仿真研究,設(shè)計并實現(xiàn)了“復(fù)雜信號環(huán)境的動態(tài)模擬軟件”,為雷達偵察設(shè)備的研制,提供了強大的外場信號環(huán)境支持。本文的主要內(nèi)容如下:1、首先,通過對比當(dāng)前已有雷達信號環(huán)境仿真技術(shù),分析它們的優(yōu)缺點,選擇合適本項目所需的理論和技術(shù)支持;再根據(jù)項目的需求分析,提出本軟件的整體設(shè)計方案,數(shù)據(jù)仿真實現(xiàn)方案和雷達脈沖信號描述字生成方案等。2、其次,分析常見制式的雷達脈沖信號,建立多種制式的雷達脈沖信號數(shù)學(xué)模型;根據(jù)雷達輻射源所處的地理位置和接收器的移動軌跡,建立雷達與接收器在三維立體空間內(nèi)的通信模型。3、然后,根據(jù)規(guī)劃的軟件設(shè)計方案及建立的數(shù)學(xué)模型,編程實現(xiàn)模擬軟件的各個核心模塊,實現(xiàn)模擬軟件的數(shù)據(jù)仿真功能,通過仿真計算得到雷達基帶數(shù)據(jù),信號環(huán)境數(shù)據(jù)和相應(yīng)的脈沖描述字。4、最后,搭建適合的測試平臺,對仿真軟件的性能和指標進行測試,驗證軟件的合理性,并對仿真結(jié)果進行驗證,確認軟件的正確性和數(shù)據(jù)的準確性。通過測試平臺的測試驗證,本項目中的復(fù)雜信號環(huán)境動態(tài)模擬軟件,在時間間隔精度為0.1s、保證數(shù)據(jù)精度和完整性的情況下,精確仿真出二十部雷達脈沖信號相互疊加作用下信號環(huán)境數(shù)據(jù),以及記錄雷達脈沖信息的脈沖描述字。經(jīng)過與其相對應(yīng)的脈沖描述字進行對照驗證,該數(shù)據(jù)滿足項目各項指標要求。
[Abstract]:With the continuous development of radar technology, the signal environment in the battlefield is influenced by the intersection of various parameters and different radar radiation signals, so the radar reconnaissance equipment located in the battlefield has higher performance requirements.In the development of new radar reconnaissance equipment, in order to accurately test the location performance of reconnaissance equipment, it is necessary to provide a real battlefield signal group environment as the experimental basis.However, it is impractical to reconstruct the signal environment by using real emitter equipment, which is influenced by many factors, such as external climate, experimental site and experimental funds.Therefore, it is of great significance and value to develop a simulation software that can deal with this problem to restore the real battlefield signal group environment.Based on the research of dynamic simulation of complex signal environment, this paper designs and implements the "dynamic simulation software of complex signal environment", which provides a powerful external signal environment support for the development of radar reconnaissance equipment.The main contents of this paper are as follows: first, by comparing the existing radar signal environment simulation technology, analyzing their advantages and disadvantages, selecting the appropriate theoretical and technical support for this project, then according to the needs of the project analysis,The whole design scheme of the software, the realization scheme of data simulation and the scheme of generating radar pulse signal description word are put forward. Secondly, the common radar pulse signal is analyzed, and the mathematical model of radar pulse signal is established.According to the location of the radar emitter and the moving track of the receiver, the communication model .3between the radar and the receiver in three-dimensional space is established. Then, according to the software design scheme and the mathematical model,Through the test and verification of the test platform, the dynamic simulation software of complex signal environment in this project can guarantee the data accuracy and integrity under the condition that the precision of time interval is 0.1 s.Twenty radar pulse signals are simulated accurately under the superposition of the signal environment data and the pulse description words to record the radar pulse information.The corresponding pulse description word is compared and verified, and the data meet the requirements of each item.
