Sine tracking model of hypersonic target in near space based on radar detecting

In view of tracking problems of hypersonic target in near space, such as large manoeuvring and difficulty to measure and so on, a new Sine tracking model based on characteristics analysis of gliding trajectory is proposed. Firstly, target of gliding trajectory has characteristics such as long distance, low energy costs and strong defending, and flight forces and motion are mainly analyzed, to reduce measure errors for model lost correlation. Then based on the full analysis of target hypersonic characteristics, non-periodic random, Sine model is built scientifically, to solve the problem that routine tracking model is only able to track low dynamic changing target. Finally, Sine model tracking on ECEF (Earth-centred Earth-fixed) coordinate is used to further improve on the hypersonic target tracking. Compared with other simulation models such as Singer and Jerk, Sine model will further improve the precision of locating and tracking.
