对不规则子阵固态有源相控阵多阶振幅量化进行理论研究,给出其设计原理与途径。研究结果表明,利用较少量化台阶数,多阶振幅量化阵可实现较低的副瓣电平。尤其对于发射阵而言,该方法有利于减少组件品种和设计成本,适于工程应用。文中给出设计实例,验证了不规则子阵多阶振幅量化的正确性。

In this paper,the theoretic research on multistep amplitude quantization for a solid-state active phased array with irregular subarrays is presented,and the designing principle and approach are given.It is shown that the lower sidelobe level of multi-step amplitude quantized array should be achieved using the fewer number of quantized steps.Especially for the transmitting array,this novel method gives the advantages of reducing the varieties of modules and devisal costs,and is suitable for engineering application.Lastly,an example is put up for validating the method.
