【Abstract】 This paper discusses the influence of the channel dropping filter in UWB radar first. A new method of designing channel dropping filter is presented. In the new method,the quadrature mirror filter based on the criteria of minimum bandwidth design is designed first, then the filter is transformed in to channel dropping filter.The results show that the filters designed by the new method have better performance.\;更多还原
