State-of-the-art research and analysis of active and passive radar reflectors and ultrasonic radar systems

This paper presents a comparative analysis of active, passive, and ultrasonic radars, focusing on operational parameters such as detection range, coverage angle, and adaptability to weather conditions. Active radars demonstrate efficiency over long distances, while passive radars are suitable for scenarios with low radio frequency emissions. Ultrasonic radars, on the other hand, are optimal for short-range detection. The results are presented through tables and charts, highlighting the advantages and limitations of each system, along with recommendations for their use in various industrial applications.
