Kriging-Based 3-D Spectrum Awareness for Radio Dynamic Zones Using Aerial Spectrum Sensors
IEEE SENSORS JOURNAL, 24(6), 9044–9058.
author keywords: 3-D spectrum awareness; Aerial Experimentation and Research Platform for Advanced Wireless (AERPAW); antenna radiation pattern; I/Q samples; Kriging interpolation; long-term evolution (LTE); propagation modeling; radio dynamic zones (RDZ); reference signal received power (RSRP); Universal Software Radio Peripheral (USRP); unmanned aerial vehicle (UAV)
TL;DR:
3-D Kriging interpolation technique provides significantly better radio maps when compared with an approach that assumes perfect knowledge of path loss, and the root-mean-square error of the signal power prediction achieved by the proposed 3-D Kriging method is notably lower compared to that of the perfect path loss-based prediction.

Analysis of UAV Radar and Communication Network Coexistence With Different Multiple Access Protocols
IEEE TRANSACTIONS ON COMMUNICATIONS, 71(11), 6578–6592.
author keywords: Coexistence; guard zone; HPPP; multiple access; sensing and communication; stochastic geometry; UAV communication; UAV radar detection
TL;DR:
Using stochastic geometry, closed-form expressions are derived to characterize the performance of coexisting UAV radar and communication networks for spectrum overlay multiple access (SOMA) and time-divisionmultiple access (TDMA) and results show that SOMA can outperform TDMA on both SRP and TC when the node density of active UAV-radars is larger than the nodes density of UAVs.
