FMCW Radar Simulation Code: Efficient and Practical Implementation

The provided code offers not only utility but also high computational efficiency for simulating frequency-modulated continuous wave (FMCW) radar systems. This implementation includes key components such as linear frequency modulation (LFM) waveform generation, mixer operation for de-chirping, and Fast Fourier Transform (FFT)-based signal processing for range detection. The simulation accurately models radar signal propagation, enabling researchers and engineers to analyze system performance through parameters like sweep bandwidth, duration, and target characteristics. Users can modify core functions to simulate various scenarios including multiple targets, different modulation schemes, and environmental effects. The code structure facilitates easy parameter adjustment for exploring radar behavior, with built-in visualization tools for analyzing beat frequency spectra and range-Doppler characteristics. This practical implementation provides valuable insights into FMCW radar working principles while maintaining computational efficiency through vectorized operations and optimized algorithms.
