摘要

阵元数太多导致前视阵列SAR系统天线成本高和设计复杂,如何以较少的阵元数获取较高的成像质量是前视阵列SAR系统面临的重难点问题.根据系统成像质量要求,结合波束扫描、栅瓣抑制等技术,本文提出一种稀疏收发天线阵的设计方法.理论分析和仿真实验结果表明,该方法在保证一定成像质量的前提下,有效降低了阵元数量,提高了系统信噪比,具有一定的应用价值.

Abstract

The large number of array elements leads to the high cost and high design complexity of forward-looking array SAR system. How to obtain higher imaging quality with fewer array elements is a difficult problem for forward-looking array SAR system. According to the quality requirements of system imaging, combined with beam scanning and grating lobe suppression technique, a design method of sparse transmitting and receiving antenna array is proposed. Theoretical analysis and simulation results show that the method can effectively reduce the number of array elements and improve the signal-to-noise ratio of the system, and has a certain application value.
