Through-the-wall radar imaging (TWRI) is receiving a considerable attention recently due to its diverse applications. One of the impinging challenges is the multipath propagation from the surrounding environment and even targets themselves. Multipath propagation produces ghost targets which populate the scene and not only create confusion with genuine targets but deteriorate the performance of compressive...
In through-the-wall radar imaging (TWRI), path-loss can result in misleading targets. The fact that distant targets experience more path-loss than near targets is an essential feature of propagating signals. This paper proposes a path-loss compensator, which reverts the unavoidable loss in power by using different path-loss models. This will be effectively done by developing and incorporating the...
Due to its diverse applications, through-the-wall radar imaging (TWRI) is rapidly growing with much attention on the application of compressive sensing (CS) and multipath ghost suppression. If not properly handled, ghosts can adversely affect the image interpretation. This paper proposes efficient ghost suppression method which exploits aspect dependence feature of the ghost under CS framework while...
In through-the-wall radar imaging (TWRI), the presence of multipath create ghost targets which can adversely affect the image reconstruction process. Unlike genuine targets, ghost positions are aspect dependent which means their position changes with the transceiver location. This paper proposes efficient ghost suppression method exploiting aspect dependence feature with compressive sensing. The signal...
In through-the-wall radar imaging, multipath propagation can create ghost targets which can adversely affect the image reconstruction process. The fact that the ghost positions changes with the radar locations which is referred to as aspect dependence has been reported as among the features distinguishing ghost from true target. This paper proposes ghost suppression method which exploit the aspect...
Technology is improving rapidly. One of the most revolutionary communication technologies that appears to be convincing and efficient is called High Altitude Platform (HAP). As any other wireless communication system, a main degrading factor of HAP Station (HAPS) propagation channel in desert and semi-desert areas is the dust storm attenuation. This attenuation increases with an increasing operational...
