Directional pattern modeling and simulation of triangular grid circular planar array antennas

Based on a long range early-warning phased array radar, the directional pattern of the triangular grid circular planar array antenna is studied. The mathematical model of triangular grid circular planar array antennas pattern is established, and its computer simulation method is described. In order to form a low side-lobe pattern, the method of Taylor circular array synthesis is used to optimize the amplitude distribution of the current excitations. The practice demonstrates that the simulation method presented is very efficient and practical.
