ex9_15 比较相参积累和非相参积累。仿真先产生信号回波。得到回拨求模的结果，计算回波的信噪比。进行非相参积累和相参积累处理，计算相参处理和非相参处理后的信噪比。(Comparison ex9_15 coherent and noncoherent. Simulation of the first echo signal. Be the result of the call-back mode for calculating the echo signal to noise ratio. For noncoherent and coherent processing, the calculation of non-coherent processing and coherent treatment of the signal to noise ratio.)

说明：  用相空间局部投影法对加噪混沌时间序列去噪或进行混沌序列与正弦信号的分离。(phase space with local law to increase the projector noise chaotic time series denoising or chaotic sequence with sinusoidal signal separation.)
