This paper investigates the technology of determining the attitude of rotating flying object moving at high speed. By installing the microwave antenna and gravity accelerometer to the rotating flying object, the Digital Signal Processing (DSP) systems inside it can receive the linear polarization electromagnetic wave emitted by the land microwave transmitter and the output signal of the accelerometer. Then the DSP systems can determine the attitude of rotating flying object in precision. Our research indicates that this technology has the advantages including the speediness of determining the attitude，low cost of systems, small size and high efficiency of anti-overloading.
