摘　　要：论文基于天线反射板与船体开口连接形式,从连接板倾斜角度、天线嵌入深度及连接板之间连接形式等影响因素,针对典型形式开展RCS(Radar Cross Section)仿真计算。由仿真结果得出面阵天线与船体共形的RCS减缩方法:天线连接板应设置一定倾斜角与船体连接,且连接板之间应避免构成直接或间接直二面角结构;天线在满足自身辐射性能的前提下,应避免嵌入深度过大;连接板与连接板之间应棱边连接,或选择半径较小的圆弧过渡半径。In this paper, based on the connection form of the array antenna reflector and hull opening, the RCS(Radar Cross Section) simulation calculation is carried out for the typical form from the influencing factors of the inclination angle of the connection plate, the antenna embedding depth, and the connection form between the connection plates. From the simulation results, the RCS reduction method of the array antenna and hull conformal is obtained. The array antenna connecting plate should be set to a certain tilt angle to connect with the hull, and the direct or indirect straight dihedral structure should be avoided between the connecting plates. The antenna is meeting its own radiation. Under the premise of performance, the embedding depth should be avoided,the connection plate and the connection plate should be connected by edges, or the arc transition radius with a smaller radius should be selected.
