摘要
研究了采用移相器的虚位技术将会产生量化副瓣的问题,进而提出了采取不同子阵划分方式来减弱或消除量化副瓣的方法,通过具体数据分别对距离波束指向方向和法线方向最近位置上出现的量化副瓣进行了分析、讨论,验证了取不同子阵划分方式能够减弱量化副瓣的影响,最后对其结果进行了仿真和分析,验证了此方法的可行性和正确性。
Using the phantom-bit technology of phase shifter digital will bring out the problem of quantization sidelobes analysed in this paper . Thus , a method of changing the subarrays partition to eliminate and restrain the quantization sidelobes is proposed. Based on separate analysition and discussion of the the quantization sidelobes with the material datas , the method of changing the subarrays partition is proved to weaken the influence of quantization sidelobe. In the end of the paper the results are analised and simulated to prove its implementability and validity.
