The invention relates to the field of atmosphere data measuring equipment measurement performance evaluation technology and specifically discloses an embedded atmosphere measuring equipment performance evaluation method. The method comprises the following steps: 1, measuring to obtain meteorological data in a flight test profile; 2, measuring missile actual flying trajectory parameters; 3, measuring pressure field data and atmosphere parameter calculation data; 4, correcting trajectory parameters to obtain reference inflow parameter; 5, carrying out aerodynamic simulation prediction, and effectively carrying out atmosphere parameter calculation by atmosphere measuring equipment; and 6, obtaining atmosphere parameter measurement accuracy of the atmosphere measuring equipment and evaluating whether measuring performance of the atmosphere measuring equipment satisfies index requirements. By the method, high-precision actual flying inflow reference atmosphere parameter can be obtained, and actual flying inflow Mach number deviation within the Mach number range of 2.0-3.5 is +/-0.03; and within the range of -10 degree to +10 degree, accuracy of angle of attack and sideslip angle is +/-0.2 degree. By the use of the high-precision reference atmosphere parameter data, measurement accuracy of the embedded atmosphere measuring equipment can be effectively evaluated.
