利用小波变换、fft实现地震波的时域、频域特征的对比分析(Comparative analysis of seismic wave in time domain and frequency domain by wavelet transform and FFT)

用STM32F103 实现三相互补输出 SPWM波，可调频率，串口通许控制，已经上机调试成功(Using STM32F103 to realize three phase complementary output SPWM wave, adjustable frequency and serial port control, it has been debugged successfully.)

通过虚拟阵元进行DOA估计，FMCW调频连续波雷达的测距测角，在matlab R2009b调试通过。( Conducted through virtual array DOA estimation, FMCW frequency modulated continuous wave radar range and angular measurements, In matlab R2009b debugging through.)
