A system tests a device under test (DUT) that includes an antenna. The system includes a probe antenna, a network emulator, and a near-field antenna. The probe antenna measures beam characteristics of a beam-locked beam emitted over the air by the antenna of the DUT as the DUT is moved relative to the probe antenna during testing of the DUT. The network emulator emulates a base station of a communications network in communications with the DUT. The near-field antenna maintains a call link between the network emulator and the DUT using surface waves between the near-field antenna and the DUT as the DUT is moved relative to the probe antenna.

An apparatus is for generating an emulated radar reflection signal of a target. The apparatus includes a radar detector configured to detect a radar signal frame emitted by a device under test (DUT), an emulation transmitter configured to generate an emulated radar reflection signal of a target being emulated, and a processor configured to generate control signals which control the emulation transmitter according to at least one characteristic of the target being emulated. The processor is further configured to determine a current radar parameter among plural possible radar parameters of the radar signal frame of the DUT, and to adapt the control signals which control the emulation transmitter according to the determined current radar parameter of the radar signal frame of the DUT.

A method and system are provided for generating a trigger signal from a radar signal received over the air from a radar under test. The method includes detecting power of the radar signal received from the radar under test at a radio frequency (RF) power detector, the radar signal including multiple bursts of RF energy in a burst pattern; identifying repeating radar frames from the burst pattern using the detected power of the radar signal, each radar frame having at least one burst; and creating trigger signals corresponding to the radar frames, respectively, by synchronizing to the at least one burst in each radar frame.

Method and system for generating trigger signals from radar signal

An apparatus includes an electrical connector. The electrical connector is configured to electrically couple a signal transmission line to another signal transmission line. The electrical connector includes a first electrical conductor and a second electrical conductor. The first electrical conductor is disposed around a center axis. The first electrical conductor is disposed azimuthally symmetric around the center axis. The second electrical conductor is disposed around the center axis and around the first electrical conductor. The second electrical conductor is disposed azimuthally symmetric around the center axis. Faces on opposing ends of the electrical connector along the center axis are configured to mate the signal transmission line and the second electrical conductor in a first plane and the other signal transmission line and the second electrical conductor in a second plane.
