Abstract: Determination of aiming advance distance and maximum correction distance is important for the correction strategy on one-dimensional trajectory correction projectile. Focusing on the problem that the resistance device of one-dimensional trajectory correction fuze has limit increased-resistance capacity, the aiming advance distance and required maximum correction distance were analyzed using probability and mathematical statistics based on the principle of the maximum number of projectiles that fall into the designated field. Results show that, when parts of the projectiles are corrected, the correction strategy is the best in condition that the aiming advance distance is half of the maximum correction range and 2 times of the standard deviation of range error of uncontrolled projectile. Taking 155 mm shrapnel as an example, the reasonableness of the correction strategy above has been verified using Monte-Carlo simulation. With small aiming advance distance and the maximum range correction, the proposed correction strategy can make the greatest improvement of the range accuracy. Therefore it is perfect for one-dimensional trajectory correction fuze which has limited resistance capacity.
