Radar systems are used for detecting and tracking objects in the air, on the ground, or in space. They operate by transmitting electromagnetic pulses and then analyzing the echoes that bounce back from objects in their path. Radar systems are commonly used in aviation, military operations, weather forecasting, and maritime navigation. They play a crucial role in providing situational awareness and enhancing safety and security in various industries. Researchers in the field of radar systems focus on developing and improving the technology to enhance performance, reliability, and efficiency in different applications. They also work on advancing signal processing algorithms, antenna design, and radar imaging techniques to achieve better resolution and accuracy in target detection and tracking.
