【摘要】：隨著雷達技術(shù)的迅猛發(fā)展,雷達體制正朝著多樣化、復(fù)雜化和綜合化方向發(fā)展,使得電子對抗面臨的電磁環(huán)境越來越復(fù)雜。如何在復(fù)雜的信號環(huán)境下實現(xiàn)雷達信號的高性能分選成為雷達對抗的一個關(guān)鍵問題。本論文研究了雷達偵察系統(tǒng)雷達信號分選方法以及分選方法的性能影響。主要分析了射頻目標(biāo)特征及其變化對分選性能的影響。本文詳細(xì)介紹了雷達信號參數(shù)以及它的變化樣式;研究了雷達信號分選流程,從預(yù)分選和主分選兩個環(huán)節(jié)梳理了雷達信號分選的主要方法;定義了分選的性能指標(biāo),根據(jù)參數(shù)分布以及分選的原理建立了雷達信號分選的數(shù)學(xué)模型,然后通過理論推導(dǎo)逐一分析了射頻目標(biāo)的每個特征變化對分選各個環(huán)節(jié)的影響,并且對分選方法中的一些影響因素做了簡要介紹。最后,編制雷達信號分選仿真軟件,使用軟件對論文中的研究結(jié)果進行了仿真驗證。驗證結(jié)果表明,本文中的分析結(jié)論具有一定的合理性,為提高雷達信號分選性能提供了依據(jù)。
[Abstract]:With the rapid development of radar technology, the radar system is developing towards diversification, complexity and integration. The electromagnetic environment of electronic countermeasure is becoming more and more complex. How to realize the high performance sorting of radar signal in complex signal environment becomes a key problem in radar countermeasure. This paper studies radar of radar reconnaissance system. The influence of the signal sorting method and the separation method on the performance of the radio frequency target is mainly analyzed. The radar signal parameters and its variation patterns are introduced in detail in this paper, and the influence of the characteristics of the radio frequency target and the variation of the radio frequency target on the separation performance are analyzed in detail. This paper studies the flow of radar signal sorting, combs the main methods of radar signal sorting from two aspects of pre-sorting and main sorting, and defines the performance index of radar signal sorting. According to the principle of parameter distribution and separation, the mathematical model of radar signal sorting is established, and the influence of each characteristic change of radio frequency target on each link is analyzed one by one by theoretical derivation. Finally, the simulation software of radar signal sorting is compiled, and the research results in this paper are simulated with the software. The results show that, The conclusion in this paper is reasonable and provides a basis for improving the performance of radar signal sorting.
