Abstract: The missile performance of anti-tactical ballistic missile (ATBM) depends on missile fuze and warhead to a great extent. In order to improve the kill probability, a simple but effective time de?lay algorithm is very important. The paper does some researches on two time-to-go algorithms, which are deduced using angle information provided by the seeker fuze and are analyzed through simulation. The simulation results show that the algorithm I is too sensitive to the noise of angle and the estima?tion error is too big. Algorithm 2 has better performance than algorithm I. GHK filter can make the steady estimation error very small. It can satisfy the request of accurate burst time control.
