雷达隐身对于水面舰船具有重要的意义。舰炮作为重要的舰面设备，无法与舰船上层建筑融为一体，其隐身性能对水面舰船雷达特性的影响较为突出。降低舰炮的雷达特征信号，使其难以被敌方雷达探测系统发现和跟踪，可以提高舰炮的生存力。舰炮隐身设计主要是对防护罩外形隐身设计。根据舰炮总体布局设计要求和隐身外形设计原则，对舰炮防护罩进行外形隐身设计，并使用物理光学法对舰炮外露部分进行RCS仿真以评估该舰炮的隐身性能。根据仿真结果，可知舰炮的强散射源在防护罩正前方（$\varphi $=90°）和两侧面（$\varphi $=0°，$\varphi $=180°），并分析强散射源产生原因。
Radar stealth is of great significance to surface warships. As ship surface equipment, the influence of naval gun stealth performance on the radar characteristics of surface warships is more prominent. Reduce the radar signature of naval gun, to make it difficult to be found and tracked by enemy radar detection system, can improve the survivability of naval gun. The stealth design of naval gun is mainly for the shape stealth design of shield. According to the requirements of naval gun and the principle of shape stealth design, design the stealth shape of naval gun shield, and take RCS simulation on the exposed part of naval gun based on physical optics to estimate the stealth performance of naval gun. According to the RCS simulation results, it can be seen that the strong scattering source of naval gun is in the front(($\varphi $=90°))and two sides($\varphi $=0°, $\varphi $=180°)of the shield, and the reason of strong scattering source is analyzed.
