针对常规波束运用到复杂传感器阵列时旁瓣较高的缺点,给出了一种适用于任意阵形和阵元指向性的传感器阵列的主瓣约束条件下的最低旁瓣优化波束图设计方法。通过计算机仿真结果表明,该低旁瓣波束形成方法相比于常规波束的旁瓣控制方法,在同等主瓣宽度的情况下可以获得更低的旁瓣级。 Aiming at the drawback that the sidelobe is high when the conventional beam is applied to a complex sensor array, a method for designing the lowest sidelobe optimal beam pattern under the mainlobe constraint of a sensor array suitable for arbitrary array and array element directivity is given. Computer simulation results show that the low sidelobe beamforming method can obtain lower sidelobe level with the same width of mainlobe compared with the sidelobe control method of conventional beamforming.
