نویسنده
چکیده
Digital Signal Processing techniques for ground surveillance RADAR has been thoroughly investigated and optimized for an improved detection of target. Using the established techniques like Pulse compression, Fast Fourier Transform and Windowing, the present work optimizes the selection of pulse coding techniques, window type and different filters.The work proposes techniques to mitigate inherent problems in RADAR Signal Processing like Range Side Lobe and Clutter. This paper covers the complete design of digital signal processing building blocks of Pulse Doppler RADAR namely, Modulation, Demodulation, Match Filtering, Range Side Lobe suppression, Doppler Processing and Clutter Reduction.Rejection of land and volume clutter(rain clutter) has been optimized. Related simulation results have been presented.
