组网探测雷达威力仿真计算软件开发Thedevelopmentofpowersimulationcalculationsoftwareofnetteddetectionradar摘要随着高科技技术武器的高速发展带来的隐身目标、反辐射导弹、低空突防和综合电子干扰这四大雷达威胁已成为影响现代战争焦点-制空权和制电磁权的重要因素。拥有全方位、立体化、多层次战斗体系和全频段、多体制、多重叠系数等技术性能的组网雷达是提高雷达“四抗”能力的较优方案。建立在成熟的计算机技术和数字信号处理技术基础上的运用计算机对组网雷达系统进行的仿真、开发仿真软件具有经济、实用、灵活等特点，因而成为国内外雷达系统和国防领域的研究热点。基于这一背景，以组网探测雷达的工作原理和数字信号处理技术为基础，运用MATLAB编程语言开发一个以包括雷达系统参数在内的参数为输入的仿真软件用于模拟组网雷达的工作过程，以雷达基本原理为基础来仿真信号在雷达外的传输过程，以数字信号处理技术为基础来仿真信号在雷达设备中的产生和处理过程，通过设定相关的雷达系统参数、目标散射模型和雷达网络参数来完成相应的编程生成雷达的检测特性曲线(ROC曲线)、探测区域的图以及计算雷达的探测范围，从而可以用来分析评估组网雷达的威力。本软件的仿真结果可用于支撑探测雷达网络布站优化及协同工作方式的研究。关键词：组网雷达；探测威力；MATLAB仿真；数字信号处理AbstractFourofradar’sthreatswhichincludestealthtarget,anti-radiationmissile,lowaltitudepenetrationandintegratedelectronicjammingbroughtbyhighlydevelopinghigh-techweaponstechnologyhavebecometheimportantfactorsofinfluencingfocusofmodernwarfare,whichareairsupremacyandmasteryoftheelectromagnetic.Nettedradar,whichhasomnibearing,three-dimensionalandmulti-layeredcombatsystemandfull-band,multi-systemandmultipleoverlappingcoefficienttechnicalperformance,issuperiorplanofimprovingtheabilityof“fourcounteraction”radar.Simulationanddevelopingsimulationsoftwaretonettedradarsystembyusingcomputersbasedonmaturecomputertechnologyanddigitalsignalprocessingtechniqueshavethecharacteristicsofeconomy,practicalandflexibility,consequentlywhichhavebecomeresearchfocusinradarsystemanddefenseindustryathomeandabroad.Basedonthisbackground,inthispaperwedevelopasimulationsoftwaretosimulateworkprocessofnettedradarbyusingMATLABprogramminglanguage.Itusesparametersincludingradarsystemparametersasinputs,simulatestransmittingprocedureofsignaloutsidetheradarsbasedonbasicprincipleofradarandproductionandprocessingprocedureofsignalinradarequipmentsbasedondigitalsignalprocessingtechnology.Bysettingarelatedradarsystemparameters,targetscatteringmodelandradarnetworkparameterstocompletethecorrespondingprogrammingtogenerateradar’sdetectionperformancecurve(ROCcurve),detectionareafigureandcalculateradar’sdetectionrange,whichcanbeusedtoevaluatethepowerofnettedradar.Thesimulationresultsofthissoftwarecanbeusedtosupportdetectionradarnetworkoptimizationandstudyofcollaborativeworkpatterns.Keywords:NettedRadar,DetectionPower,MATLABSimulation,DigitalSignalProcessing目录第一章绪论..........................................................................................................................11.1研究的背景、目的和意义.....................................................................................11.2国内外研究现状.....................................................................................................11.3本文的主要工作.....................................................................................................2第二章雷达仿真原理...........................................................................................................52.1雷达的基本原理.....................................................................................................52.2单基地雷达的仿真原理.......................................................................................62.2.1发射机模块.................................................................................................62.2.2回波信号产生模块.....................................................................................72.2.3接收机模块.................................................................................................92.2.4测量分析模块...........................................................................................122.2.5人机交互模块...........................................................................................122.3双/多基地雷达与组网雷达.................................................................................122.3.1双/多基地雷达.........................................................................................122.3.2组网雷达...................................................................................................132.4本章小结...............................................................................................................14第三章单基地雷达的仿真实现.........................................................................................153.1不同条件下的雷达方程的仿真............................................................................153.1.1理想条件下基本形式的雷达方程的仿真...............................................153.1.2考虑损耗下的雷达方程的仿真...............................................................153.2单基地雷达的仿真实现.......................................................................................153.2.1发射机模块的实现...................................................................................153.2.2回波信号产生模块的实现.......................................................................173.2.3接收机模块的实现...................................................................................193.2.4测量分析模块...........................................................................................233.3本章小结...............................................................................................................25第四章组网雷达仿真实现........................................................
