The invention relates to a semi-physical simulation system multi-source object simulation device pointing accuracy calibration method according to which a calibration system is formed by a standard imaging detection device and a multi-source object simulation device. The standard imaging detection device is used for testing an optical axis pointing angle and a view field coverage area of each channel, and view field overlap areas of all channels are found. A geometric centre of the view field overlap areas is set as a center axis of the object simulation device, all the channels are adjusted to the center axis of the object simulation device via an initial position compensation method, and therefore multi-source object simulation device pointing accuracy can be calibrated. During calibration processes, neither hardware nor a mechanical structure needs adjustment, and multichannel composite precision of the multi-source object simulation device can be calibrated just via fixed compensation of an initial position.

The invention provides a photoelectric signal simulation error analysis method. The method includes the following steps of: selecting a photoelectric signal simulation error analysis index, establishing a photoelectric signal simulation error model, carrying out a semi-physical simulation test for the error analysis index, and obtaining experimental data required for calculation of the error analysis index; instructing the error analysis index to perform calculation and measurement range conversion, and calculating an underlying index in the error model according to the experimental data; constructing a judgment matrix, calculating the weight of the error analysis index, and performing consistency check based on the judgment matrix; and obtaining the final photoelectric signal simulation error according to error analysis index calculation and consistency check. For an imaging detector, the error model is established by studying the theory and method of analysis of photoelectric signalsimulation errors, and the error analysis is completed by using the measured data. Through the photoelectric signal simulation error analysis, the simulation model can be checked, the fidelity of optical signal simulation can be analyzed and evaluated, and the confidence degree of the semi-physical simulation test results can be ensured.
