Based on beam control technology of one-dimension phased-array fuze, the paper deduced the optimal burst Angle and burst delay algorithm and researched an improved Kalman algorithm.

Fuze must obtain information from the echo of target if it wants to accurately control the explosive spot according as the target-missile approaching status.

Beacon fuze works in the way of wireless data communication, bases on the fuze technology of radio instruction, in order to realize the control of the optimal explosion height.
