NawfalMotii79/PLFM_RADAR ? reverse-engineered prompt

I want to build a complete open-source phased array radar system, something low-cost for researchers and drone developers to experiment with. The radar should operate around 10.5 GHz using Pulse Linear Frequency Modulation. A core feature needs to be full electronic beam steering, allowing it to scan a wide area without any mechanical movement.

I'd like designs for two versions: a standard model with about a 3km range and an extended 20km version that uses more powerful GaN amplifiers.

This is a full system project, so please generate all the necessary files. This includes the hardware schematics and PCB layouts for a modular design (power, RF, processing boards), the FPGA firmware for heavy signal processing like pulse compression and Doppler FFT, and the code for an STM32 microcontroller to manage all the peripherals. Finally, create a simple Python GUI that shows a live radar view with targets plotted on a map and integrates with a GPS/IMU for position correction.
