A script that allows you to create signal masks and detect new signals using hackrf

Usage:

./hackrf_tscm_sweep.sh --mask     # Run for a while to get the signal mask. Then close
./hackrf_tscm_sweep.sh --scan     # Scanning for new signals
./hackrf_tscm_sweep.sh --compare  # Detecting new signals
./hackrf_tscm_sweep.sh --reset    # Reset DB

Example of usage:

# Connect HackRF
# Run for 10+ minutes and stop by pressing [ENTER]
└─$ ./hackrf_tscm_sweep.sh --mask
>>> GET SIGNAL MASK
>>> Starting SWEEP SCAN
SWEEP_PID: 80994
MERGE_PID: 81016
Press [ENTER] to stop scanning ...

<<< scan_1640529973 IMPORTED
File -> scan_1640529983
<<< scan_1640529983 IMPORTED

# Run for scanning
└─$ ./hackrf_tscm_sweep.sh --scan

# In this example, a signal from the Ajax MotionCam was detected
└─$ ./hackrf_tscm_sweep.sh --compare
>>> COMPARE TABLES SCAN_MASK with TSCM_MASK
