Abstract
According to a surveying and mapping instrument and method for a wide-area spatial channel map through multi-unmanned aerial vehicle (UAV) cooperation, a measurement signal emission unit generates and emits a measurement signal, a measurement signal multi-UAV cooperative receiving unit receives the measurement signal transmitted through a wireless channel, extracts an effective multipath component from the measurement signal, and frames the effective multipath component and corresponding time and location information for storage, and transmits stored channel data to a channel data fusion processing unit offline, and the channel data fusion processing unit fuses the channel data in terms of space, time, and frequency dimensions, and completes missing channel data to construct a complete wide-area spatial channel map.
