摘要：

Recently, unmanned aerial vehicle (UAV)-enabled wireless power transfer (WPT) has received great attention as a promising technology for providing stable to energy-constrained devices by navigating three-dimensional (3D) space, particularly in challenging environments such maritime networks and smart cities. Additionally, UAV-enabled radar sensing gained significant key future 6G networks, it enables high-accuracy various applications, target detection tracking, surveillance, environmental monitoring, well autonomous UAV operation. In this regard, we investigated integrated (ISWPT) systems that combine WPT operations on unified hardware platform, sharing the same spectrum of resources. order accurately sense multiple targets efficiently at time, propose method jointly designing transmit waveform altitude, taking into account fundamental trade-off between performance with desired beam pattern harvested devices. We first developed an effective obtain optimal altitude solving non-convex optimization problem. Based this, another efficient, low-complexity exploring novel optimizing its parameters reduce computational complexity thereby lower consumption UAVs. The numerical results verify proposed significantly improves both performance, substantially reduces complexity.
