A glass substrate architecture for mounting RF components may be configured for heat dissipation. Existing millimeter wave radiofrequency (RF) systems mount the radiofrequency integrated circuits (RFICs) on a printed circuit board on the opposite side of a heat sink, making it difficult to dissipate heat away from the RFICs during operation. This architecture mounts the RFICs directly to a back side of a glass waveguide substrate, and thermally couples the top side of the RFICs to a conductive pad on the underlying printed circuit board with a thermal pathway to the heatsink. This leads to a much more effective dissipation of heat away from the RFICs and eliminates the need for additional cooling systems or throttling the performance of the radar system.

This invention proposes a method and system for reconstructing radio frequency (RF) signals with variable-number time-frequency structure constraints. This invention effectively reduces striped background interference and random fluctuations, significantly improving the resolution of the dominant time-frequency components of the RF signal. The method adaptively tracks the dynamically changing number of effective time-frequency components in different time regions, avoiding false detections and missed detections caused by blind searches in the entire time and frequency domains, and accurately extracting the instantaneous frequency evolution structure of non-stationary, variable-number, and overlapping RF components.
