Avoid vehicle collision

It is Radar System design and signal prcessing code based on standard algorithm .this is vey important for biggener those who are working on Radar signal processing area.This code contain various chapter. this is basically chapter No4

各种信噪比估计算法，包括ls，lms，qam，噪声统计等(A variety of SNR estimation algorithms, including ls, lms, qam, noise statistics, etc.)

说明：  小波分析的应用是与小波分析的理论研究紧密地结合在一起地。现在，它已经在科技信息产业领域取得了令人瞩目的成就。(Application of wavelet analysis and wavelet analysis theory closely together to. Now, it has been in the field of information technology has made remarkable achievements.)

Locally linear embedding(LLE)是一个经典的流形学习降维方法，通过LLE发现高维数据潜在的内在维数，可以简化计算、方便可视化处理等。(Locally linear embedding (LLE) is a classic manifold learning dimensionality reduction method, discovered by LLE potential inherent high dimensional data dimension, the calculation can be simplified to facilitate visual processing.)

提取指纹特征点的matlab代码，很有用，利用自适应阈值进行分割，再进行频域增强，根据八邻域纹线编码进行特征提取。(Extracted fingerprint feature points of the matlab code, useful, adaptive threshold segmentation, and then increased in frequency domain, the eight neighborhood ridge coding for feature extraction.)
