LSS-FMCWR-1.0: Multiband FMCW Radar Low-altitude target Detection Dataset

For each type of drone, echo data of targets within a distance of 5–12 meters were collected using K-band and L-band radars. To facilitate better usage of the data, the dataset format has been standardized with the naming convention AA-TIME-BB-CC-DD-LK-FF. 'AA' represents the drone type, with values ranging from 01 to 06: 01 for DJI Mavic 2, 02 for DJI Phantom, 03 for DJI Matrice 200 V2, 04 for DJI M350, 05 for DJI M600, and 06 for fixed-wing drones; 'BB' represents the modulation period, with values of 0.3 or 1.0 ms; 'CC' indicates the bandwidth; 'DD' is the distance unit of the target; 'LK' denotes that data were collected simultaneously with L-band and K-band radars.

If the data were collected using only the L-band radar, it will be indicated accordingly, the same applies for K-band radar data. 'FF' represents the data sequence number. The collected data matrices have the file suffix ".mat", and each matrix is of size 150*6000.
