Radar altimeters have emerged as fundamental components in unmanned aerial vehicle (UAV) systems, providing precise altitude measurements for safe and reliable operation. This article presents a comprehensive analysis of radar altimeter performance metrics relevant to UAV applications. We evaluate factors such as range, precision, and responsivenes

Radar altimetry provides a powerful tool for acquiring 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 reliability of these measuremen
