Bistatic backscatter
WebMay 24, 2024 · Performance of Ambient Backscatter Systems Using Reconfigurable Intelligent Surface Abstract: Reconfigurable intelligent surface (RIS) has been proved effective in improving the performance of communications. In this letter, the effect of RIS on individual links in ambient backscatter communications is examined. WebIn physics, backscatter (or backscattering) is the reflection of waves, particles, or signals back to the direction from which they came.It is usually a diffuse reflection due to …

WebBasically, WP-BackCom is divided to three categories: monostatic backscatter (e.g. RFID tag), bistatic scatter (BS), and ambient backscatter (AB) [11]. In [12], bistatic scatter (BS) radio was ... WebThe meaning of BACKSCATTER is the scattering of radiation or particles in a direction opposite to that of the incident radiation due to reflection from particles of the medium …
WebAnalysis of bistatic echo extends coverage and increases the data density within the monitoring area of an HF radar network. Figure 1 is a schematic diagram of an HF radar bistatic receive site with a transmitter at a separated location. Radar remote units can receive both backscatter/bistatic echo from circular/elliptical time-delay cells WebWe propose a model for a bistatic backscatter system coverage map based on the receiver selectivity, receiver sensitivity, and geometric …
