相干激光主动成像与跟踪技术研究的中期报告 Abstract:Thispaperpresentstheresearchprogressofcoherentactiveimagingandtrackingtechnologyinthemid-term.Firstly,thebasicprinciplesandcharacteristicsofcoherentlaserimagingtechnologyareintroduced.Then,theresearchoncoherentlaserimagingsystem,includingthedesignandoptimizationofopticalsystem,theselectionandcontroloflasersourceanddetector,theimagereconstructionalgorithmandthesystemperformanceevaluation,isreviewed.Finally,theresearchprogressoncoherentlasertrackingtechnologyissummarized,focusingonthetrackingalgorithm,thetrackingsystemdesignandperformanceevaluation,andtheexperimentalresults.Theproblemsandchallengesfacedbycoherentlaserimagingandtrackingtechnologyarealsodiscussed,andthefutureresearchdirectionsareproposed. Keywords:Coherentlaserimaging,tracking,opticalsystemdesign,lasersource,detector,reconstructionalgorithm,performanceevaluation. Introduction Coherentlaserimagingandtrackingtechnologyisauniqueimagingandtrackingtechnologythatusescoherentlaserlighttoprovidehigh-resolution,high-sensitivityandhigh-speedimagingandtrackingcapabilities.Ithasbeenwidelyusedinmilitary,industrial,biomedical,andaerospacefields,suchasreconnaissance,surveillance,navigation,inspection,andmedicaldiagnosis.Thetechnologyhasbeenrapidlydevelopedinrecentyears,andmanynewresearchresultsandachievementshavebeenobtained.Thispapersummarizestheresearchprogressofcoherentlaserimagingandtrackingtechnologyinthemid-term,aimingtoprovideacomprehensiveandsystematicreviewofthecurrentstateoftheartandfutureresearchdirections.
