Abstract

The invention discloses a Ka-frequency-band fixed-orientation dual-polarization all-solid-state millimeter-wave cloud radar. The millimeter-wave cloud radar comprises an all-solid-state transmitter (1), an antenna housing (5), an ortho-mode transducer (3), a dual-channel receiver (10) and the like. Output signals of the all-solid-state transmitter (1) reach an antenna (4) through a circulator (2) and the ortho-mode transducer (3) and are radiated towards the sky through the antenna housing (5); echo signals are processed by the dual-channel receiver (10), a digital receiver (11), a signal processor (12) and a display control computer (13) and provided for a far-end computer (15) through a communication system (14); a power distribution system (16) provides needed power; and test signals generated by a frequency synthesizer (9) pass through a power divider (6), a coupler A (7) and a coupler B (8) to be used for testing. According to the millimeter-wave cloud radar, a novel tool is provided for cloud observation, the size is small, the structure is simple, the reliability is high, and radar is applicable to long-time continuous observation to cloud.

Description

technical field

[0001] The invention relates to a millimeter-wave cloud radar, in particular to a Ka-band fixed pointing dual-polarization all-solid-state millimeter-wave cloud radar. Background technique

[0002] The existing millimeter-wave cloud radar includes: magnetron or traveling wave tube electric vacuum microwave tube transmitter, scannable antenna with servo system, circulator, frequency synthesizer, single-channel receiver, digital receiver, signal processor, Display and control computer, communication system, remote computer and power distribution system. The magnetron millimeter-wave transmitter has a short life and poor Doppler velocity extraction ability, and the traveling wave tube millimeter-wave transmitter has a short life and is expensive, and is not suitable for long-term continuous observation of clouds; the antenna with a servo system makes the radar structure complex , without radome protection, the radar observation is affected when there is precipi...
