This paper describes an approach which can reduce envelope delay effectively to improve traditional filter. In some
applications, traditional filter is applied to get the envelope of signal, but there is long envelope delay using traditional
filter which is not suitable for real time systems, such as ground moving target detection in wireless sensor network. This
paper presents a weighted filter approach to reduce envelope delay.
