A STUDY OF FEATURE EXTRACTION FOR mmW RADAR BY USING BISPECTRUM TECHNOLOGY
双谱用于毫米波雷达目标特征提取的研究

In mmW radar system, SNR affect heavily on radar range. To lower the SNR demand of target recognition, a new approach of feature extraction based on the bispectrum technique is presented. The feature vectors defined from bispectrum have high stability even when SNR is very low. Thus, the sensitivity and range of mmW radar are improved.
