摘要

In this paper, an extended SURE procedure is proposed to denoise radar I/Q orthogonal complex signals with Doppler phase shift using complex wavelet. Waveshrink has proven to be a powerful tool for the problem of signal extraction from noisy data. A key step of the procedure is the selection of the threshold parameter. Donoho and Johnstone propose of the threshold based on a SURE procedure for real signals. In this paper, we first review the minimax threshold selection procedure and then propose to extend the use of SURE procedure for denoising radar signals with complex-valued discrete wavelet transforms. At last, an example is used to show that the extended SURE procedure is an effective method for denoising radar signals.
