MATLAB Simulation of OFDM-Based Radar System with Code Implementation

This article explores MATLAB-based simulation of Orthogonal Frequency Division Multiplexing (OFDM) radar systems. The simulation package includes three MATLAB m-files accompanied by detailed documentation. OFDM, a widely adopted wireless communication technology, is increasingly being implemented in radar systems due to its inherent advantages. We provide a comprehensive analysis of OFDM technology applications in radar systems, discussing both benefits and limitations. The MATLAB implementation covers key signal processing components through three core files: 1. OFDM signal generation module implementing IFFT operations and cyclic prefix insertion 2. Radar target modeling with range-Doppler processing algorithms 3. Signal reception and demodulation chain featuring FFT-based decoding We present detailed simulation results with reliability and accuracy analysis, examining parameters like bit error rate and target detection probability. The discussion extends to practical implementation considerations for real-world radar systems, including hardware constraints and channel effects. Finally, we propose optimization strategies for enhancing system performance, such as adaptive modulation techniques and improved channel estimation algorithms, to boost radar reliability and operational efficiency.
