In the present study, a regional localization system is proposed based on the variation of the scattering field in ultrawide band (UWB) frequencies. The system uses the UWB antennas to transmit and receive the sweep sparse signal in the measured area. Subsequently, the compressed sensing (CS) algorithm is employed for localization. To increase the positioning accuracy, the randomness of signal distribution should be improved. Different from the previous designs, the scattering obstacles are introduced between the target and the antennas. Through simulation and experiment, a localization system composed of two transmitters and one receiver working at 10–20 GHz is proposed, leveraging the UWB source antennas and grid metal barriers. By complying with the sparse reconstruction algorithm of the CS method, the positioning accuracy of 1.4 mm is obtained in the area of 40 × 40 mm2 at 40 mm distance. The system is capable of locating in small areas effectively based on simple setup, and potentially applied to human‐computer interaction of wearable devices and other local positioning applications.

“…Nowadays, the detection for super-low altitude target above diverse environments becomes a complicated and practical problem in a wide range of fields such as radar surveillance, 1,2 target detection and recognition, [3][4][5] and remote sensing 6,7 and so forth. The electromagnetic (EM) scattering characteristics of the super-low altitude target above environment are quite different from that in free space.…”

A modified facet‐based weighted four‐path model is presented to analyze the Brewster effect of super‐low altitude target above terrestrial environments. In this approach, the facet‐based weighted four‐path model (FWFPM) is established to simulate the mutual interactions between the super‐low altitude target and terrestrial environment. Gauss antenna radiation pattern is introduced to modify the FWFPM. The hybrid PO‐MEC method is applied, where the physical optics (PO) is utilized to calculate the scattering field from each facet, and the method of equivalent currents (MEC) is used to compute the scattering field from the edge structure. The validation of the proposed method is verified by the example of a super‐low altitude missile model above a rough surface. The Brewster effect of a super‐low altitude aircraft above diverse terrestrial environments is studied. Moreover, the influences of relative permittivity, the roughness of environment, and the target's height on Brewster angle have been analyzed in detail to provide some useful conclusions.
