摘要
对岸射击时,采用雷达观测,存在杂波多、噪声过大、难以精确获取目标参数的缺点,采用光电系统观测,又易受天气和作用距离的影响,二者都有局限性。传统火控解算方法原理上存在一些不足,又依赖于射表,从而影响整个火控系统的精度。通过分析,提出了基于GPS下观测方法,利用大地主题算法中的Boring算法,建立了定位数学模型和精度模型,克服了先前的缺陷,精确确定了目标坐标。应用解外弹道方程,利用四阶龙格-库塔法求取射击诸元,提高了精度,采用DSP技术,缩短了解算时间,确保解的实时性。通过模拟仿真及数据精度分析,该方法为舰炮对岸射击提供了新的参考。
Fired at the shore, because of using radar system, target parameters were hard to obtain accurately. By use of optical-electronic system, it was liable to have weather effect and action range effect. The two sides both had limitation. Traditional fire control computation method had some disadvantages in theory, and it relied on the fire tables so as to have influence on fire control system accuracy. By means of analysis, a kind of observation method based on GPS was brought forward. With the help of Boring calculation method, the positioning mathematics model and precision model were set up. These models overcame previous shortcomings, and confirmed accurate coordinate of the target. Through exterior ballistic computation, by means of four order solution of Runge-Kutta to get fire parameters, the fire accuracy was improved. By use of DSP technique, the computation time was shortened, and real-time capability was insured.
