圆形基阵由于其几何对称性,波束随不同方位无畸变等优点,特别适用于全景观察声纳雷达系统,国外有很多声纳基阵采用圆柱型基阵。但圆柱阵有它的缺点,一个无指向性水听器组成的均匀同相激励的圆基阵,其理论副瓣级达-8dB。在实际情况下,由 Because of its geometric symmetry, the beam has no distortion with different azimuths and so on, it is especially suitable for the panoramic observation sonar radar system. Many foreign sonar arrays use cylindrical array. However, the cylindrical array has its shortcomings. A circle array with uniform in-phase excitation consisting of a non-directional hydrophone has a theoretical sidelobe level of -8dB. In reality, by
