| Abstract: | An algorithm based on two integrators is described.This method suits situation whose background has a big fluctuation.It can track the fluctuation in the background noise,and adjust the detection threshold adaptively.Power weighted integration algorithm can be used when the system has a limited storage and needs a large integration time.It has a good performance during simulation. |
