Inappropriate clothing pressure will make the wearer feel uncomfortable, affecting the work efficiency and health of the human body. Therefore, the measurement and distribution of clothing pressure play an important role in the comfort of clothing pressure. Starting from the concept and generation of clothing pressure, the theoretical research of clothing pressure is summarized, including the impact of contact mechanics mechanism, human body shape and different clothing on human body pressure. From the direct measurement method and indirect measurement method, the measurement method and principle of clothing pressure are analyzed respectively. The research status of measurement of clothing pressure by sensor method and soft mannequin method is introduced. The problems of garment pressure measurement are pointed out, and the future direction of garment pressure research is forecasted. the pressure is verified experimentally by using fiber Bragg grating sensor. The sensor has the advantages of simple structure and good measurement accuracy. The results show that the sensor has good sensitivity and linearity, which is suitable for garment pressure testing environment and has a good development prospect.","PeriodicalId":114868,"journal":{"name":"International Conference on Optoelectronic Information and Computer Engineering (OICE)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129290617","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, the mathematical model of mixed medium ground is established by Monte Carlo method to represent complex ground, and the time-domain signal scattering model is established based on the unit decomposition method. The correlation between echo signals of complex ground and single medium ground is studied by using this model, and the complex ground echo signal is analyzed by wavelet time-frequency transform. The simulation results show that, compared with the single medium ground, the complex ground mainly affects the peak amplitude of the echo signal, and has little influence on the peak position. The simulation and analysis provide a 1 theoretical basis for the ranging control of the IR-UWB fuze on the complex ground.","PeriodicalId":114868,"journal":{"name":"International Conference on Optoelectronic Information and Computer Engineering (OICE)","volume":"101 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128842579","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, with the increased squint angle, the imaged swath is obviously reduced due to the large range cell migration. To extend the reduced swath, a new spaceborne wide swath sliding spotlight mode with a high squint angle is proposed in this paper. Besides azimuth beam steering to improve the azimuth resolution, antenna beam is also steered in elevation to improve the swath width. The imaging principle of the proposed imaging mode is described in detail, while its corresponding flowcharts of SAR system design and imaging processing are given. Furthermore, the beam steering law of the designed system example with azimuth resolution of 0.5m and swath width of 20km is given, while the imaging result of the designed scene with three targets is given. Both simulation results validate the proposed imaging mode in the high squint case.","PeriodicalId":114868,"journal":{"name":"International Conference on Optoelectronic Information and Computer Engineering (OICE)","volume":"151 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133509719","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
