摘要:
随机噪声雷达具有良好的抗干扰性，与合成孔径技术的结合能够使其具有成像能力。然而，由于发射信号无固定的解析表达，传统的成像算法不能直接用于随机噪声SAR成像。本文在波数域成像算法的基础上研究了一种适用于随机噪声SAR的成像算法，得到了有效的二维输出，实验验证了输出具有良好的性能指标。同时，在压制噪声干扰条件下，验证了随机噪声SAR成像过程具有良好的抗干扰性能。Random noise radar has well-defined anti-interference performance, and it can get the imaging ability combined with synthetic aperture technology. However, the traditional imaging algorithm could not be applied to SAR imaging due to the fact that emission signal does not have analytic ex-pression. In this paper, imaging algorithm based on the wave number domain is proposed. At the same time, in the suppression of noise interference, SAR imaging process is of good performance of anti-interference.
