弹道偏差 [dàn dào piān chā]
ballistic deflection
- 采用传统的平均燃速压力指数来预侧该类发射药的内弹道性能，将出现明显的偏差。
It will appear an evident error when interior ballistic behaviors of this kind of high-energy propellant are evaluated by traditional average burning rate pressure exponent. - 这种方法与惯用迭代方法相比，其优点是将落地点射程偏差和方位角偏差的二元迭代分解成两个一元迭代，这样不仅可大大提高弹道迭代的收敛速度，而且可以满足任何需求的迭代精度指标。
Comparing the old iteration algorithm, the rapid iteration algorithm is which decomposes binary variable iteration, which include the hit-point range error iteration and hit-point azimuth error iteration, to be two unary iterations. - 摘要针对洲际弹道导弹，在分析加速度计测量误差和陀螺漂移误差对导弹视加速度影响的基础上，给出了中制导段惯性系统对速度和位置的误差传递模型，对给定的惯组误差系数偏差进行了纯惯性导航制导误差计算。
Taking intercontinental ballistic missiles as objects under research, and based on the analysis of the influence of accelerometer measurement error and gyroscope excursion error on the apparent acceleration, the error transfer model of the inertial system in a midcourse guidance segment for velocity and location is given, and the pure inertial navigation guidance error is computed with the given IMU error coefficient deviations.
