The research demonstrates a significant advancement in vehicle intelligence and road safety. Utilizing custom-designed code and MATLAB's simulation tools, it successfully achieves precise determination of a vehicle's speed, position, and direction using passive radar, effectively addressing the common issues of noise and unclear images prevalent in standard radar systems. It critiques the limitations of traditional simple radar systems in complex automotive environments and proposes a superior approach utilizing passive radar technology. Unlike conventional radar systems that use active emissions, passive radar leverages existing electromagnetic signals, offering a more covert, energy-efficient, and potentially more reliable detection method.
