Orthogonal Frequency Division Multiplexing OQAM is a prominent modulation technique widely employed in wireless communications systems. COFDM effectively transmits data by dividing the available bandwidth into numerous subcarriers that are modulated independently. These subcarriers are orthogonal to each other, ensuring minimal interference and ena
Radar altimeters employ electromagnetic signals to calculate the distance between the instrument and a ground. This principle allows for high-precision height assessment, making radar altimeters invaluable in various industries. Accurate measurements are achieved through the evaluation of the time delay between transmitted and received waves. By a
Precise altimetry refers to the accurate measurement of height or elevation. Radar technology plays a crucial role in achieving this precision. By emitting electromagnetic waves and analyzing the time it takes for these waves to return from a target, radar systems can determine the distance between the sensor and the target, thus enabling precise
