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

Radar altimetry provides a powerful tool for acquiring high-resolution terrain maps. By measuring 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 accuracy of these measurements by
