Packaging-Codesign for Thec Development of a High-Resolution MIMO-Radar-Module for Automated Guided Vehicles

Compact radar systems with the ability to detect objects in space (4D radar) with high resolution (<tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$4^{\mathrm{o}}$</tex> azimuth, <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$6^{\mathrm{o}}$</tex> elevate) require at least 144 channels. 1 channel is equivalent to the combination of a transmitter and a receiver antenna. Radar modules for use in 3D radar with 12 channels are state of the art. The article shows how such systems can be realized cost-effectively by cascading 3D radar modules. Such an approach places high demands on the packaging technology for both functional and size reasons. In order to select the appropriate technology and to consider the technology-related influences of the packaging on the function of a radar module, a packaging codesign approach is presented, which disassemble the five steps of setting up the requirements (1), disassemble the radar module into functional assemblies (2), creating an architecture (3) and technology concept (4) and codesign phase (5) and leads the designer successively to the final layout. Finally, the realization of a radar module for a driverless transport system is used to show that the method presented is highly likely to lead to functional radar modules in the first step.
