Ground Based SAR Data of Cardboard box with Aluminium Bottles for Anomaly Detection

The dataset consists of 155 raw Ground Based SAR (GBSAR) data examples for anomaly detection outside of visible area. Specifically, 5 aluminium bottles are set in the card box.
4 different scenes are recorded:
1. without anomaly (50 examples)
2. with anomaly placed instead of the first bottle (35 examples)
3. with anomaly placed instead of the third bottle (35 examples)
4. with anomaly placed instead of the fifth bottle (35 examples)

Each example is stored as matrix in .txt format. Matrix is size of 1024x24 (1024 frequency points, 24 GBSAR steps)

Raw data is obtained using developed GBSAR system. It works in stop-and-go mode with 1 cm step size and total aperture of 24 cm. GBSAR sensor is FMCW (Frequency Modulated Continuous Wave) radar with central frequency at 24 GHz and 1.3 GHz wide bandwidth. FMCW radar periodically transmits sawtooth signal every 166 ms. Wave polarization of FMCW radar is set to vertical.
