Wind profiler radar signal is subject to contamination from various non-atmospheric signal. A new wind profiler radar signal processing method based on wavelet is presented for the suppression of ground clutter using adaptive threshold. By using the discrete multi-resolution analysis, we developed the adaptive wavelet domain thresholding method, which allow us to identify the coefficients relevant...
Wavelet based image compression is getting popular due to its promising compaction properties at low bit-rate. Zerotree wavelet image coding scheme efficiently exploits multi-level redundancy presented in transformed data to minimize coding bit. In this paper, a novel compression algorithm for weather radar data based on zerotree coding is presented. Considering the dependence of radar data, an efficient...
The SAR remote sensing images are interfered by noises during the detection and transmission, a method based on wavelet packet and level dependent adaptive threshold is proposed in this paper. By using this method, the SAR images can be decomposed in a more elaborate method compared to the traditional wavelet transform, and the noises in the SAR images are eliminated by the adaptive threshold method...
A method for achieving weather radar data compression with parallel adaptive coding is presented. Considering the specialty of it, some efficient pre-processing algorithms for the data such as coordinate transformation algorithm, scalar filter algorithm and vector field holding algorithm are given first. Then the parallel adaptive coding algorithm is used to compress the pre-processed data. Experimental...
