LSS-FMCWR-2.0：Multi-band multi-angle FMCW radar low-altitude target detection dataset

The dataset contains a total of 90 data points.The copyright of the low-altitude target Echo Dataset of Multi angle and Multi band Frequency Modulated Continuous Wave Radar (LSS-FMCWR-2.0) belongs to the Marine Target Detection Team of Naval Aviation University, and the editorial department of Radar Journal has editing and publishing rights. Readers can use this data for teaching, research, etc. for free, but they need to cite or acknowledge it in the paper report results.The radar settings, acquisition scenarios, and signal processing flow of the LSS-FMCW R-2.0 dataset can refer to the paper "Multi band and Multi angle FMCW Radar low-altitude target Detection Dataset (LSS-FMCW R-2.0) and Feature Fusion Classification Method".

The DJI M350, quadcopter drone, DJI Wu 2, and DJI Yu 2 each contain 20 sets of data, the AC311 helicopter contains 2 sets of data, and the simulated flying bird contains 4 sets of data. The LSS-FMCWR-2.0 dataset is constructed by naming the data. In order to facilitate the use of the dataset, the format of the dataset is uniformly named as AA time collection angle BB-CC-DD-L/K (FF), where AA represents the type of drone and ranges from 01 to 06; The collected angles include 0, 60, 90, 120, and 180 degrees; BB represents the modulation period, with values of 0.300 and 1.024 (in ms), CC represents the bandwidth, and DD represents the distance unit where the target is located; L/K represents data collected in the L-band or K-band, where L represents data collected by the L-band radar and K represents data collected by the K-band radar; FF represents the number of data numbers.

The matrix file suffix for collecting data is ". mat".Several points to note: - L-band radar data are real, which does not affect time-frequency analysis; - Some parameters in L-band data collection remain unchanged in position, so the data remains unaltered.
