一种利用多核解卷积提高雷达角分辨力的方法

A Method of Improving Radar Angular Resolution via Multikernel Deconvolution

解卷积方法可以提高雷达的角分辨力,但传统的解卷积算法对噪声很敏感,且有可能无解。给出了多核解卷积方法的最优滤波器,分析了多核解卷积的输出信噪比,指出其抗噪声性能要优于单核解卷积。最后将多核解卷积的方法运用到单脉冲雷达中。仿真结果表明,在输入信噪比为20dB的情况下,该方法还能够得到很好的结果。

The method of deconvolution can be used to improve radar angular resolution. The traditional method of deconvolution is sensitive to noise, and there could be no solution in some case. This paper presents an optimal filter of multikemel deconvolution, and analyzes the output SNR, and shows that the anti-jaming performace of multikernal deconvolution is better than that of singlekernel. This method can be used in monopluse radars. The simulation shows that this method has good result under the 20dB input SNR.
