A pulse radar ranging system

摘要

To reduce measurement errors due to changes in the environment temperature of a pulse radar ranging system, the system has a measurement channel and a reference channel. In the measurement channel containing the antenna 7 and measurement target 8, the normal measurement is performed by processing the echo RX1 from the target 8. In the reference channel containing signal delay means 15, a reference echo RX2 is processed to obtain temperature compensation information.
