Research on tracking technology of the hypersonic aircraft based on IMM

In recent years, with the development of the aerospace all over the world, the hypersonic aircraft who works in the near space plays an important role in the area. Its speed is quick, cruise altitude is high and penetration ability is strong, so it puts forward a new difficult problem to the whole world, the research of tracking technology also becomes more and more popular. According to this point, the text introduces the characteristic of the hypersonic aircraft, builds the flight model, finishes the application of IMM in tracking technology of the hypersonic aircraft and gets an ideal effect comparatively.
