A Multi-Channel Joint Thresholding One-Bit SAR Imaging Method

This is the authors' abstract. We don't add key points for this paper.

In multi-channel synthetic aperture radar (SAR) systems, one-bit quantization scheme is used to simplify system hardware implementation and reduce data volume. However, the high-order harmonics introduced by one-bit quantization, severely reduce imaging quality. To mitigate the impact of harmonics, this article proposes a multi-channel joint thresholding one-bit SAR imaging method. The experimental results show that the proposed method achieves superiorer imaging quality than one-channel one-bit SAR imaging in terms of various indicators, and approaches that of high-precision imaging.
