针对舰艇编队防空反导背景下舰炮与防空导弹的火力兼容问题，以舰炮全航路拦截反舰导弹为研究对象，基于空域格模型对空域资源的量化描述，采用弹道微分方程进行火控解算，建立了基于空域格的火控诸元快速解算模型，解算出舰炮对反舰导弹全航路拦截情况下，舰炮弹丸炸点占用的空域资源和时间资源。对占用的空域和时域资源进行时空匹配，给出在舰炮抗击末端，基于空域格的舰炮与导弹火力兼容判断的方法，对解决舰炮与导弹火力兼容问题提供了一定的补充和借鉴。

This paper addresses the issue of firing compatibility of the naval guns with the air-defense missiles in air defense and missile defense of warship formation. Taking the interception of the anti-ship missile by the naval gun during its full air route as the object of study and based on the quantitative description of airspace resource by using the airspace grid model，this paper adopts the ballistic differential equation to solve the fire control problem and builds a rapid calculation model of fire control units based on the airspace grid. Under the condition of the full-course interception of the anti-ship missile by the naval gun，the occupied airspace resource and time resource by naval gun projectile are calculated.The matching of the occupied spatial and temporal resources is carried out，and a new method based on airspace grid is given，which is helpful to solve the problem of firing compatibility between the naval guns at the launch end with the missiles.
