用Ziegler--Nichols整定公式来求P,PI,PID的个参数，其中Gc是校正器的传递函数,kp为比例系数， Ti为积分时间常数，Td为微分时间常数，输入参量vars为带迟滞--惯性环节模型的KT τ(With Ziegler- Nichols tuning formula to seek P, PI, PID' s parameters, which Gc is the corrector transfer function, kp is proportional coefficient, Ti the integral time constant, Td for the differential time constant, input parameters vars as with hysteresis- inertia model of the KT τ)

修改后的LABVIEW小波（调用MATLAB）(LABVIEW modified wavelet (call MATLAB))

用窗去除噪声，达到良好的去噪效果.通过不同窗的比较，得到满意的效果。(to discris the noise by a window)

换能器散射回波信号声强预测，可自拟发射和接收换能器的类型及指向性，海底散射强度，得到不同条件下的散射回波信号声强(Transducer scattering echo sound intensity forecasts can be self-transmitting and receiving transducers of the type and point to the seabed scattering intensity, obtained under different conditions of scattering echo signal sound intensity)
