Abstract :
A lossy data compression algorithm based on wavelet transform modulus maxima denoising (WTMM-D) has been proposed. Firstly, analysis for radar raw data is presented to identify data characteristics and correlation. Then, we transform the data format and compare the experimental results using different lossless compression algorithms to compress the transformed raw data. Finally, a method based on WTMM-D is presented, which is using a high-performance lossless compression algorithm to compress the reconstructed coefficients of WTMM-D. Experimental results show that the proposed algorithm can compress raw data efficiently under the premise of a certain distortion.
