The rapid rollout of wireless local area networks (WLANs) has provided a ubiquitous source of signal transmissions that may be exploited for surveillance applications using passive bistatic radar (PBR) and passive multistatic radar (PMR) systems. In this study, a series of experiments were conducted to examine the feasibility of using IEEE 802.11 wireless fidelity (WiFi) transmissions for detecting...
Power-Law detector based on DFT is developed to detect a moving dim target under heavy infrared background. Because that the grey-scale value of a pixel in an image occurs fluctuation when a target passes by, this fluctuation can be viewed as a weak transient signal, and the Power-Law processor has advanced performance on transient signal detection. Firstly, a time window, length of L frames, is introduced...
