DistUAV-Tomo3D-1.0：Distributed UAV Radar Multiple Transmit-Receive Single-Pass Tomographic SAR 3D Imaging Dataset

The dataset described pertains to a four-unit distributed UAV radar system used for multiple transmit-receive single-pass TomoSAR imaging. The distributed radar system used for data collection operates in the P-band, employing a time-division waveform system with a carrier frequency of 425 MHz and a signal bandwidth of 60 MHz. The parameters of the radar system . This system works collaboratively through four UAV platforms, forming 10 equivalent phase centers in the elevation direction, which enables TomoSAR imaging during a single pass. The data acquisition experiment was conducted at the Beijing Jinhai Lake Airport, with flight altitudes ranging from 220 m to 280 m, a platform movement speed of 2 m/s, a slant range to the scene of 600-1800 m, and an elevation baseline length of approximately 60 m. The dataset primarily includes three parts: pre-processed radar echo data, distributed radar 2D image data, and distributed radar 3D image data. It serves as empirical data support for advanced research in distributed radar signal synchronization methods and TomoSAR imaging technology. Preliminary research and technical validation based on this dataset have been conducted by Beijing Institute of Technology, resulting in distributed radar images of the experimental scene with a 3D resolution of approximately 2.7m × 1.1m × 2.5m.
