摘要：

Two technical schemes to improve the ability to locate and catch the echoes are put forward. In the case of continuous strong noise, constant false alarming rate (CFAR) can be realized by dynamically adjusting the contrasting level. A method of using former frame of data to approximate to the actual situation is also given. The help of these two measures can obtain higher capture rate.
