The pulsed X and Ka-Band Radar doppler MIRA-10 and MIRA-35 (formely named MIRA-36) are unique in performance and durability and deliver a calibrated Doppler spectrum of cloud droplets in up to 1024 height steps for a vertical range up to 15 km at a finest time resolution of 20 Hz (no coherent averaging). The wide dynamic range and the very high system sensitivity allow a tomography of cloud structures even in thin ice layer. Several antenna sizes can be installed stationary or in a trailer as mobile platforms.
