MATLAB Simulation for Radar Signal Echo Detection Using IFFT Algorithm

Using the IFFT (Inverse Fast Fourier Transform) algorithm for radar signal echo detection can be effectively simulated in MATLAB environment. This approach enables comprehensive analysis of radar signal characteristics through frequency-domain processing, where the IFFT operation converts frequency-domain data back to time-domain for echo detection and parameter extraction. The simulation allows adjustment of critical algorithm parameters such as windowing functions, zero-padding factors, and sampling rates to observe detection performance under various scenarios. Key MATLAB functions like ifft() can be implemented with proper signal conditioning, including hanning windows for spectral leakage reduction and coherence processing for phase preservation. Through systematic parameter variation and signal input modifications, researchers can investigate radar signal processing principles including range resolution, Doppler effects, and signal-to-noise ratio optimization. This simulation framework enhances understanding of IFFT applications in radar systems and develops practical skills in digital signal processing implementation.
