Emulating UAV Air-to-Ground Radio Channel in Multi-Probe Anechoic Chamber

This paper proposes to use ray tracer to simulate unmanned aerial vehicles (UAV) air-to-ground (A2G) radio channels in various propagation environments and then to emulate (“replay”) the acquired channels in multi-probe anechoic chamber for the purpose of testing UAV network terminal devices. The emulation accuracy of A2G channel by polarized plane wave synthesis algorithm assuming far-field is addressed, and emulated channel properties in the ascending process of UAV are evaluated.
