The design and implementation structure of high-speed pulse shaped filter is discussed in this paper.

FPGA realization of base band interpolator pulse shaping filters;

According to the wave analysis based on stable stochastic theory,applying white noise to drive the designed shaping filter,interference model of ocean wave is obtained.

A new method for constructing shaping filters was proposed and proved.

One is suboptimal control,this technique is simple and practical, but its control performance is poor; the other is optimum control, this technique attains by using the modeling filter to change the coloured noise into white noise and extending the system model,it needs estimating and modeling the disturbance,so the algorithm is comple.

And the relationship of the peak value, peak frequency, bandwidth of a narrow band stochastic process with the corresponding parameters of the shape filter is deduced.

In this paper the rocket of 122mm, 20km is exampled, CADET is used in random ballistics system(RBS) with the action of random wind by use of sharping filter when the differential equations of sharping filter and angle motion equations of ballistics are allied.
