Abstract :
A novel narrow-bandwidth, multi-frequency continuous-wave (MFCW) ranging system to measure the distance of a weather balloon is introduced. Compared to the pulsed system, it has advantages of high accuracy, strong noise-rejection ability, narrow bandwidth and low cost. The key points in the system and test results are presented
