Develop a phased array radar system using Pulse Linear Frequency Modulated (LFM) modulation. The system should include electronic beam steering, signal processing (pulse compression, Doppler FFT, MTI, CFAR), and a modular design with separate power management, frequency synthesis, and RF boards. Implement a Python GUI for user interaction and integrate GPS/IMU for real-time position correction. The system should be open-source and support both short-range (3km) and long-range (20km) applications.
