# AERIS-10 PLFM Phased Array Radar

> Skill by [ara.so](https://ara.so) — Daily 2026 Skills collection.

AERIS-10 is an open-source 10.5 GHz Pulse Linear Frequency Modulated (PLFM) phased array radar. It comes in two versions: **AERIS-10N (Nexus)** with 3 km range using an 8×16 patch antenna array, and **AERIS-10E (Extended)** with 20 km range using a 32×16 slotted waveguide array and 10 W GaN amplifiers. The system uses an XC7A100T FPGA for signal processing, an STM32F746xx MCU for system management, and a Python GUI for visualization.

## Getting Started

### Prerequisites

```bash
# Python GUI
python --version   # 3.8+ required

# FPGA toolchain
# Install Xilinx Vivado (2022.x or later recommended)
# https://www.xilinx.com/support/download.html

# STM32 firmware
# Install STM32CubeIDE or arm-none-eabi-gcc toolchain
arm-none-eabi-gcc --version

Python GUI Setup

git clone https://github.com/NawfalMotii79/PLFM_RADAR.git
cd PLFM_RADAR/9_Firmware/9_3_GUI

pip install -r requirements.txt
python radar_gui.py

Building STM32 Firmware (GCC)

cd 9_Firmware/9_2_STM32

# Using Make (if Makefile present)
make all

# Flash via ST-Link
make flash
# or
st-flash write build/aeris10.bin 0x08000000

Building FPGA Bitstream (Vivado TCL)

cd 9_Firmware/9_1_FPGA

# Non-interactive build
vivado -mode batch -source build.tcl

# Open project interactively
vivado aeris10_fpga.xpr
