Alignment: Typographic term to indicate the position of each type is perfectly aligned across a base line. The term in full is base alignment.

Meanwhile, an accurate nonlinear filter model for moving base alignment is built, which meets the requirements of alignment velocity and accuracy in air-to-air missiles.

By establishing the system model of moving-base alignment velocity match, the factors that influenced the transfer alignment were analyzed, such as lever arm effect, flexible vibrations, etc.
