Abstract
A system emulates multipath effects of a radar signal transmitted by a radar and reflected from an emulated target and an emulated surface. The system includes RTSs configured to generate and transmit emulated echo signals having different phases in response to the radar signal, where a first RTS is configured to emulate the emulated target, receiving the radar signal via a direct path, and at least one second RTS is configured to emulate at least one ghost target corresponding to the emulated target; and a controller configured to control the RTSs to generate and transmit the emulated echo signals at the different phases, which correspond to the RTSs receiving the radar signal from the radar transmitter and the radar receiver receiving the emulated echo signals from the RTSs over different combinations of the direct the indirect paths to replicate interference effects caused by multipath propagation.
