基于VB／MATLAB的前兆资料小波分析程序的实现(Based on the VB/MATLAB wavelet analysis of the precursor process information to achieve)

说明：  此程序实现构造Daubechies小波基,求解小波尺度函数离散整数点的值和实现尺度函数经伸缩后的离散值采用双尺度方程求解小波基函数(The Program for Daubechies wavelet construction, solving the discrete wavelet scaling function and implementation of an integer point value after scaling function by the expansion of discrete values using the two-scale wavelet basis function equation)

对EBPSK(Extended binary phase shift keying)调制雷达系统的特点，本文将其与传统的LFM(Linear frequency modulation)雷达系统进行综合性能比较。(he overall performances of EBPSK(Extended binary phase shift keying) modulation and LFM(Linear frequency modulation) radar systems are compared. First, the target detection performance base on CFAR(Constant False Alarm Rate) of two systems are analyzed under several conditions. As the time-delay is relatively large, the detection performance of EBPSK modulation radar system is better than LFM radar system. EBPSK modulation signals can combat the effect of Doppler spread on system performance in HF(High Frequency) channel.)

ESPRIT是“Estimating signal parameters viarotational invariance techniques”的缩写，含义是“借助旋转不变技术估计信号参数”，它是由Roy[221等人于1986年提出的另一种基于子空间的DOA估计方法。 应用领域 　　侧向定位 信号处理 思想 　　ESPRIT的思想在于，将传感器阵列分解为两个完全相同的子阵列，两个子阵中每两个相对应的阵元具有相同的平移，即要求阵列具有平移不变性，每两个位移相同的阵元匹配成对。所幸的是实际中许多阵列满足这个条件，比如等距直线阵。(ESPRIT is "Estimating signal parameters viarotational invariance techniques" acronym, meaning "With ESPRIT estimation of signal parameters", it is by Roy [221, who in 1986 proposed DOA estimation method based on subspace another. Applications Lateral positioning signal processing Thinking ESPRIT thinking that the sensor array is divided into two identical sub-arrays, each of the two sub-arrays of two corresponding array element has the same translation, which requires an array with translation invariance, the displacement of each of the two identical arrays yuan matching pairs. Fortunately, many of the actual array satisfy this condition, such as equidistant linear array.)
