In the complex electromagnetic countermeasure environment, in order to improve the detection ability is of great significance for aircraft application. Scientific and rational decomposition of direction-finding index plays an important role in system optimizing and product performance improving. In this paper, the direction-finding accuracy of passive detection device based on aided inertial information is calculated and analyzed. The accuracy demand of passive detection device is decomposed into accuracy of the attitude control algorithm, inertial device and structure installation. Through the calculation and analysis, the index of passive detection device will be 1.93°, when the direction-finding accuracy is 2°. The analysis results show that the index decomposition method is reasonable and effective, and can meet the requirements of the overall design, which provides a basis for the overall design.
