舰炮一维修正弹校正诸元误差和预测误差试射

摘要

The conventional test firing method of incontrollable bomb is not fitting for one dimension trajectory correction projectile because their work theories are different. Firing errors and need to test firing are analyzed when shipborne gun fire correction projectile, and the new test firing method to correct firing data error and forecasting error is demonstrated. Firstly, the method to calculate two errors is put forward and the number of test firing bombs is demonstrated by analyzing the preci⁃sion of regarding the deviation between detecting point of fall and predicted point as firing data error, and the precision of re⁃garding the deviation between detecting point of fall and forecasting point of fall as predicting error. Secondly, firing data er⁃ror and forecasting error are corrected both at the range direction and landscape orientation. It is proved that the new test fir⁃ing method can improve firing accuracy by simulating and supposing every firing error data.%由于工作原理不同，舰炮使用传统无控弹试射方法不适用于一维弹道修正弹。分析了舰炮使用一维弹道修正弹射击误差构成和试射的必要性，提出了一维弹道修正弹校正射击诸元误差和预测误差试射新方法。首先通过分析对海射击以实际观测弹着水柱与提前点偏差作为发射诸元误差的精度，以及以预测弹着落点与实际观测弹着水柱偏差作为预测误差的精度，提出了求取诸元误差和预测误差的方法，论证了试射发数；然后从距离上和方向上校正诸元误差和预测误差。假设各误差值，通过仿真计算表明，按新方法试射能够显著提高射击精度。
