Lincoln Laboratory Paper Review: RFSoC’s Contributions to the Development of Next-Generation All-Digital Phased Arrays (3)
Preface The U.S. National Weather Service operates a network of 150 dual-polarization Doppler weather radars to detect and forecast hazardous weather and to generate quantitative precipitation estimates. Dual‑polarization phased‑array radars (PPARs) support multiple approaches that can substantially increase volumetric sampling rates, thereby providing significant benefits for severe‑weather warnings and precipitation estimation. The agile electronic beams of dual‑polarization phased‑array radars also enable enhanced data quality and coverage tailored to operational priorities, improve clutter suppression through adaptive adjustment of the minimum elevation angle beam pattern, and eliminate beamwidth broadening caused by scanning.

Comparative Evaluation of Low-Power RF Performance in RFSoCs—DAC/ADC Characteristics, Phase Noise, Crosstalk, and Latency
Introduction: RFSoC is currently widely used in communications, radar, and satellite‑communication applications. However, the practicality of low‑level radio‑frequency (LLRF) control systems in accelerator environments—where stability is of paramount importance—has yet to be evaluated.

Lincoln Laboratory Frontier Literature Review: Scalable Array Technology for RF Fusion Applications (2)
High‑performance radar systems employ phased arrays to steer and focus the antenna’s radiation in desired directions, thereby maximizing link margin. Conventional implementations of these systems are typically limited to specific radar modes; however, next‑generation designs are expected to take on additional roles, supporting other wireless applications such as communications and surveillance. This multi‑purpose utilization of a single radio‑frequency resource is known as RF fusion and is enabled through the integration of simultaneous transmit‑and‑receive (STAR) technology. In this paper, we examine the key research areas that must mature before scalable STAR arrays can be deployed for integrated RF applications.

Lincoln Laboratory Frontier Paper Review: How Phased-Array Architectures Enable Scalable Integrated Sensing and Communications (1)
Phased-array systems can directly support integrated sensing and communication (ISAC) as well as other functionalities, while also incorporating in-band full-duplex (IBFD) technology. It has been demonstrated that digitally controlled self‑interference cancellation techniques can establish isolation between transmit and receive subarrays within a single aperture for a limited number of elements.
