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 thorough analysis of radar altimeter performance metrics relevant to UAV applications. We evaluate factors such as range, precision, and sensitivity in div

In the increasingly complex electromagnetic spectrum, ensuring reliable video transmission amidst potential interference is paramount. COFDM (Coded Orthogonal Frequency-Division Multiplexing) systems offer a robust solution by utilizing orthogonal subcarriers and error correction codes to mitigate signal degradation. However, intentional jamming ca
