its makes to similarly other parts of the systems are electromagnetic spectrum [16]. Infrared laser waves. The distance motion and types of the hit and coming waves frequency signal have analyzed the compare to echo noises depends upon the shape of pulses. That lilt to improved performances using a technique known as pulse compression. The waves transmission of time taken for the distance travels one nautical mile. To hit and reflect the waves to the antennas. For examples, the nautical miles define as a 1952m then calculate the distance divided by the light speed is 299792458 m/s. As shown in figure 5.
