舰炮零位检测方法与实现

Checkout and Realization of Shipborne Gun Null-position

提出了白天或夜间利用远方可见固定目标(距离大于3km)检测舰炮零位,来取代在夜间利用星体检测舰炮零位的传统方法,给出了检测数学模型,并对检测误差进行了分析。该检测方法在通用型舰炮零位检测仪中得到了具体应用与实现。试验证明:该检测仪能适用于各种口径舰炮,检测精度达到0.1mrad。

This paper advances a new way to check in place of the traditional way of checkout the nullposition of the shipborne gun according to the starry object at night. In this new way, the null-position of the shipborne gun is checked according to the distant fixed visible object（over the range of 3km）at daytime or night. Its mathematical model of the checkout is described, and its checkout error is analysed. This new method of checkout has been realized and put into practice of the general shipborne gun null-position indicator. It has been proved through the experiments that this indicator is applicable to shipbone guns of various calibrer, and the precision of the checkout can reach 0.1 mrad.
