Radar altimeters have emerged as essential components in unmanned aerial vehicle (UAV) systems, providing precise altitude measurements for safe and reliable operation. This article presents a thorough analysis of radar altimeter performance metrics relevant to UAV applications. We examine factors such as range, accuracy, and sensitivity in diverse

Radar altimetry provides a powerful tool for capturing high-resolution terrain data. By calculating the time delay between transmitting and receiving radar signals, precise elevation measurements can be obtained. COFDM (Coded Orthogonal Frequency Division Multiplexing), a sophisticated modulation scheme, enhances the robustness of these measurement
