Aiming at the need of high-precision measurement of the surface temperature of the structure of the test object in a supersonic rocket sled test,this paper proposes and verifies a method of measuring the surface temperature of the structure based on calibration technology and data algorithm optimization.Based on high-precision acquisition,storage testing,and reliability testing of the surface temperature parameters,the influence of long response time of the temperature sensor on temperature characteristic testing is analyzed.A test system is constructed to calibrate the time response characteristics of the temperature sensor.The test results show that the accuracy of the surface temperature measurement is significantly improved by using the calibrated data modified by the data processing algorithm.
