A real-time terminal-based radar system that visualizes network signals and device activity as animated radar sweeps. Monitor WiFi networks, Bluetooth devices, and system connections with professional radar display effects.

• Professional Radar Display: Beautiful terminal-based radar with smooth sweeping animations
• Real & Simulated Data: Toggle between actual WiFi/network scanning and simulation
• Signal Types: WiFi (≋), Bluetooth (β), Cellular (▲), Radio (◈), IoT (◇), Satellite (★)
• Interactive Controls: Filter signals, adjust speed, select for detailed analysis
• Authentic Radar Behavior: Signals appear when swept and persist until next detection cycle
• Range Rings & Distance Markers: Professional 10m, 20m, 30m, 40m range indicators
• Signal Information Panel: Detailed signal analysis with strength, type, and timing data
• Cross-Platform: Works on macOS, Linux, and Windows terminals

# Clone and run
git clone https://github.com/e6a5/radar.git
cd radar
go run main.go

• Go 1.23.2 or later
• Terminal with color support

Real Data Collection (Default Mode):

• WiFi Networks: Scans actual networks with signal strength and human-readable names
• Network Activity: Monitors active connections and system processes
• Device Discovery: Finds devices on local network with distance estimation
• Authentic Radar Physics: Signals appear when radar beam sweeps over them and persist until next detection cycle

Visual Features:

• Smooth Range Rings: Professional circular range indicators at 10m intervals
• Radar Sweep Animation: Realistic rotating beam with trailing effects
• Signal Persistence: Detected signals remain visible until next sweep, just like real radar
• Real-time Information: Signal count, speed, and mode displayed in status bar
• Signal Details Panel: Select any signal for detailed analysis (strength, distance, bearing, history)

Press S to toggle simulation mode if real data collection is unavailable.

Privacy Note: On first run, you'll be asked for permission to collect device data. Your consent is saved and you won't be prompted again. To revoke consent, delete the file ~/.radar_consent.
