The E8719A from Keysight is an Automotive Radar Target Simulator that has a frequency range from 76 to 81 GHz with exceptional gain flatness complemented with over-the-air calibration feature enabling accurate target simulation. It has a simulation distance from 3 to 300 meters with a distance accuracy of ±5 cm and supports Doppler simulation up to ±500 km/h. This simulator has an instantaneous bandwidth of 5 GHz and is available as a single or multi-target (3 targets, 2nd, and 3rd target is fixed distance) solution. It employs the U9361M receiver calibrator for over-the-air calibration which enables accurate target simulation and provides a highly repeatable, metrology-driven automated routine. The measured losses can then be fed back into the simulator, where adjustments can be made to ensure a well-calibrated path for the overall radar target test. It provides options for horn antennas and front-end brackets and an additional calibrated IF port for connection to external devices.
Imaging radars, also known as 4D radars with their increased antenna array provide a “visual” 3D image of the environment, a massive improvement over the standard radar sensors. These improvements come with higher demand for test equipment, such as more bandwidth (BW) and better distance accuracy. The E8719A improves over previous generations of radar target simulators (RTS) with a full 5 GHz of instantaneous BW, no separation or shifting of available BW within the usable ranges, and just one setting. This comes with exceptional gain flatness and better-simulated distance resolution, ready to address the needs of any radar sensor on the market from 76 to 81 GHz.
