The MU radar is one of the most multi-functional atmospheric radar with an active phased array system consisted of 475 antenna elements. The MU radar has a monostatic circular antenna with a diameter of 103 m, which can be divided to 25 independent subarrays. Tropospheric and lower stratospheric observations (2-25 km), mesospheric observations (60-90 km), and ionospheric observations (80-500 km) are available.
The MU radar imaging observation system installed in 2004 can switch the operational frequency between 46.0 MHz to 47.0 MHz in every Inter-Pulse Period (IPP). The receiver system is also upgraded to 29-channel digital receivers. The received signal of each sub-array can be independently detected, and combined in the digital processing. This new feature enables us the multifunctional observation of Coherent Radar Imaging (CRI) and Range Imaging (RIM) techniques.
