Abstract: Pulse radar is the backbone measurement and control equipment in our country. Because of its narrow beam, it is always difficult to capture and track in the measurement and control task. For many years, measurement and control technicians have been studying and exploring the simulation actual combat training in different ways. The traditional RF simulator is realized by the up-conversion mode, which has huge equipment and high price. This paper introduces the basic composition of measurement and control equipment and the formation process of sum and difference signal in pulse radar. Based on the practical radar system, the software module is used to realize the control hardware of the upper computer system and the information transmission with the radar equipment. C-band radar analog signal is generated by AD9361 RF chip. Through the test and verification on the radar equipment, the software radio technology is successfully realized to generate the C-band RF signal, which solves the problem of insufficient actual combat training means for equipment personnel, further improve equipment personnel tracking capture and emergency disposal ability, is an important means to test the technical and tactical performance of the equipment.
Key words : pulse radar,;sum-difference signal;simulator,;AD9361

    隨著我國航天事業(yè)的發(fā)展,,近年來我國先后裝備了一批用于航天工程任務(wù)的測(cè)控設(shè)備[1]。這些設(shè)備由中心機(jī)遠(yuǎn)程統(tǒng)一管理和調(diào)度,,實(shí)現(xiàn)設(shè)備的組網(wǎng)和自動(dòng)化運(yùn)行,。在測(cè)控任務(wù)中,目標(biāo)航跡追蹤的準(zhǔn)確,、及時(shí)與否,,直接關(guān)系到任務(wù)的效果。因此,,在日常作戰(zhàn)演練中,,針對(duì)目標(biāo)航跡如何進(jìn)行模擬、仿真也得到了高度的重視,。對(duì)應(yīng)的,,一些具有代表性的方法也不斷地提出。仿真的有效性一方面取決于對(duì)目標(biāo)特性的刻畫,,另一方面取決對(duì)設(shè)備特性的分析,。目標(biāo)特性取決于對(duì)應(yīng)的應(yīng)用場(chǎng)景,文獻(xiàn)[2]~[5]都是以飛機(jī)為基礎(chǔ)參考物,,提取其參考的空中目標(biāo)對(duì)應(yīng)的若干種特征進(jìn)行的系統(tǒng)仿真,。航跡跟蹤設(shè)備包括對(duì)應(yīng)的預(yù)警設(shè)備、測(cè)控設(shè)備等,。在測(cè)控系統(tǒng)中,,由于發(fā)射信號(hào)的波束較窄,其大范圍搜索截獲能力受到一定限制,,單純依靠手動(dòng)搜索發(fā)現(xiàn)目標(biāo)較為困難,。為了保證雷達(dá)能及時(shí)抓到目標(biāo)并盡早穩(wěn)定跟蹤,在設(shè)計(jì)和使用時(shí)通??紤]采用數(shù)據(jù)引導(dǎo)以提高搜索截獲效率[6-9],。隨著設(shè)備的使用,,引導(dǎo)的精度需要實(shí)時(shí)校準(zhǔn)。
