The optimization of Radar Cross-Section (RCS) using Animation-Based Visualization techniques for miniature Ultra-Wide band (UWB) vehicle radars is presented in this study. The radar is designed to enhance detection of static and dynamic road hazards, such as animal carcasses or debris, with a range of up to 1 kilometre. The optimization methodology was centered on striking a balance between RCS reduction, power efficiency, and detection accuracy. With a spatial precision of roughly one meter, the UWB technology broadcasts small pulses while using little power. According to simulation results, detection is effective up to 1000 meters, and the amplitude of the received signal decays exponentially with distance, which is consistent with the behavior of theoretical route loss. For instance, the system's range-dependent sensitivity is confirmed when the signal amplitude decreases from 5.06 mV at 100 meters to 1.45 mV at 1000 meters. These findings indicated the critical role of pulse modulation, adaptive beam steering, and intelligent power management in maintaining reliable detection in dynamic environments. The optimized radar system demonstrates strong potential for integration into Advanced Driver-Assistance Systems (ADAS), contributing to enhanced vehicle safety and autonomy. Future research will investigate real-time adaptation strategies and validation in diverse environmental scenarios to further improve performance.
