Digital array MST (Mesosphere-Stratosphere-Troposphere) radar and method for receiving and transmitting signals

Abstract

The invention discloses a digital array MST (Mesosphere-Stratosphere-Troposphere) radar, which is characterized by comprising an antenna unit (1), a data processor (8) and the like, wherein a frequency source (5) is connected with a digital transmitting-receiving assembly module (4), the digital transmitting-receiving assembly module (4) is connected with a feeder network matrix (3), the feeder network matrix (3) is connected with a last-stage transmitting-receiving assembly module (2) which is connected with the antenna unit (1), the antenna unit (1) is connected with the last-stage transmitting-receiving assembly module (2), the last-stage transmitting-receiving assembly module (2) is connected with the digital transmitting-receiving assembly module (4) by the feeder network matrix (3), the digital transmitting-receiving assembly module (4) is connected with a digital transmitter-receiver, the digital transmitter-receiver is connected with a digital beam combining module (6) which is connected with a signal processor (7), the signal processor (7) is connected with the data processor (8), and the data processor (8) and a remote terminal (9) are connected with a system monitoring device (10). The digital matrix MST radar has the advantages of better stability, small volume, excellent reliability and convenience for installation and debugging.

Description

technical field [0001] The invention relates to a radar technology, in particular to a digital weather radar and a method for transmitting and receiving signals thereof, in particular to a digital array MST radar and a method for transmitting and receiving signals. Background technique [0002] MST (middle-stratosphere-troposphere) radar is a high-sensitivity phased array radar operating in the VHF frequency band (generally around 50MHz), mainly used to measure the middle layer (the highest altitude exceeds 100km), the stratosphere and the troposphere atmospheric wind field. Since the 1980s, radar technology and analysis methods for detecting the middle atmosphere have been continuously improved, and transmitters have begun to use all-solid-state transmission technology. [0003] At present, there are more than 20 MST radar stations in operation in the world. These radars are divided into two systems, one is a high-power centralized transmission system, and the other is a d...
