【摘要】 利用地震波进行弹丸落点定位时,地震波传感器的布阵方法及解算模型直接影响着弹丸落点定位的准确性。针对55～157mm口径弹丸落点定位的要求,基于时差法建立了弹丸落点定位数学模型,分析了基于地震波的弹丸落点定位方法在3km×3km靶场区域内的适用范围;利用MATLAB对定位误差进行仿真计算,确定了模型参数,验证了菱形阵列的适用性。更多还原

【Abstract】 With the aid of seismic waves to position the projectile impact point,the arraying method and resolving model of seismic wave’ s sensors have direct influence on the accuracy of position testing.Aimed at the requirements of 55-157 mm caliber projectile impact point positioning,the mathematical model of projectile impact point positioning was established according to the method of time difference of arrival,the effective detection range of the projectile impact point positioning method in the area of 3 km×3 km was analyzed based on seismic waves.By use of MATLAB simulation to analyze and calculate the positioning error,the model parameters were determined,and the applicability of the diamond-shaped array was verified.更多还原
