Abstract: A system for receiving a radar signal transmitted by a radar device under test (DUT) includes: a plurality of antennae disposed in an array of rows and columns; a plurality of radar target simulators (RTS's), one or more of the plurality of RTS's being selectively connected to each of rows or columns of the plurality of antennae. The plurality of antennae are adapted to receive signals selectively from the one or more RTS's connected to the column or row, and to transmit to the signals to the DUT. The system also includes a switching matrix adapted to selectively switch between selected antennae in each of the columns or each of the rows of the plurality of antennae to connect selected respective RTS's of the plurality of RTS's to selected active antennae of the plurality of antennae in a time division manner.

Abstract: A hardware-in-the-loop (HiL) test system is for testing sensor fusion of an advance driver assistance system (ADAS). The ADAS includes a plurality of sensors and an electronic control unit (ECU) processing outputs of the sensors. The HiL test system includes a three-dimensional (3D) scenario simulator for generating drive scenarios including objects in a surrounding environment of a simulated vehicle, and a sensor target emulator for generating emulated sensors inputs to the plurality of sensors corresponding to the drive scenarios generated by the 3D scenario simulator. The sensor target emulator is configured to synchronize the emulated sensor inputs by interpolating a current location of the objects from parameters extracted from the drive scenarios.

Abstract: A sensor device is provided for measuring current in an electrical circuit of a PCB, including a coaxial connector mounted on a tab in the PCB having an inner conductor and a concentric outer conductor, where the tab is formed by a gap through the PCB along a portion of a perimeter surrounding the coaxial connector; a sidewall conductor formed on sidewalls of the tab and connected to ground plane; and resistors mounted on the PCB and arranged along the portion of the perimeter surrounding the coaxial connector, each resistor being connected between the inner conductor and the sidewall conductor. Current from the electrical circuit flows in a first direction through the ground plane creating a first magnetic field, and flows in a second direction between the sidewall conductor and the inner conductor through the resistors creating a second magnetic field, where the first and second magnetic field partially cancel.
