Imaging of Distributed Objects in UWB Sensor Networks the conventional range migration algorithm known from GPR or similar applications is given by a simulated example. The example shows disadvantages of the range migration algorithm for imaging in UWB sensor networks. Images obtained by the new proposed algorithm are easier to interpret and their quality is much higher.作者: Pudendal-Nerve 時間: 2025-3-22 00:51
