A　detecting　algorithm　of　the　pulse　waveform　of　radial　artery　based　on　continuous　wavelet　transform　(CWT)　is　proposed　in　this　paper.　At　present,　the　hemodynamic　parameters　can　be　detected　widely　by　using　the　instrument　based　on　the　pulse　wave　of　radial　artery.　But　operators　are　demanded　to　have　certain　medical　knowledge　to　artificially　detect　a　waveform　used　to　compute　hemodynamic　parameters,　thus　limiting　its　application.　As　a　result,　we　propose　a　new　algorithm,　making　use　of　wavelet　analysis,　to　detect　pulse　waveform　of　radial　artery.　Experiment　results　show　that　this　algorithm　has　good　accuracy,　can　improve　the　intelligence　of　hemodynamic　parameters　detecting　instrument,　and　can　simplify　operation,　which　benefits　popularization　of　hemodynamic　parameters,detection　in　family　health　care.
