초록

This study examines the results of the array modules corresponding to the transceivers of phased array radars utilized for space debris monitoring. The phased array radar for space debris surveillance examined in this study utilizes the S-band radar frequency and is a digital radar system. However, the transmitter-receiver module is power-consuming and generates heat to satisfy the long distance of the radar. The array modules in this study utilized a common water-elongation path to increase the power supply efficiency such that the full digital radar can be fabricated. The measured characteristics of the single array modules of space debris radar were within an output frequency range of 2.9 to 3.35 GHz and power of at least 56 dBm in 300 µs with a pulse flatness of less than 0.5 dB in this frequency band. The maximum duty of 10% was satisfied. The noise figure of the receiver satisfied the characteristics of at most 3.21 dB.
