For power transmission line detection, the multiple lasers of different wavelengths are used to location. Because of the sophisticated effects of environmental light and background elements, it's difficult to extract the laser spot. So, this paper presented a method of hybrid-laser image spot extract based on HSV space SVD for power transmission line detection, which the multiple laser spot in hybrid-laser...
Without the need of active switches, a heterogeneous integrated retrodirective/beam-switching phased array is proposed in this paper. Its topology is complementary to the one we proposed in the literature. With left-handed synthesized transmission lines in microstrip form, the current version can behave identical to a reflection-type retrodirective array in the lower band, but automatically turns...
