Enabling High-Resolution Radar in the D-Band Using SiGe MMICs

High-resolution radar technology in the D-Band offers unique opportunities for precision sensing in both industrial and scientific applications. This talk presents recent advances in the development of silicon-germanium (SiGe) Monolithic Microwave Integrated Circuits (MMICs) enabling radar systems with instantaneous bandwidths of up to 56GHz. Such systems achieve multi-target resolution in the millimeter regime, down to 2.5mm, while maintaining an absolute ranging accuracy on the order of 1µm. These capabilities open new perspectives for high-precision imaging, non-destructive testing, and short-range metrology. We will discuss the circuit design challenges and system-level considerations, including wideband signal generation, and integration aspects specific to SiGe technology. Measurement results from realized prototypes will highlight the achievable resolution and accuracy, demonstrating the potential of SiGe MMICs as a cost-effective platform for scalable, high-performance radar solutions. The workshop will provide insight into both the enabling hardware concepts and the broader application space of next-generation high-resolution radar.
