Analysis and processing method and system based on all-sky meteor radar signal

Abstract

The invention belongs to the field of radar technology, and relates to an analysis and processing method and system based on all-sky meteor radar signals, aiming to solve the problem that the analysis and processing of all-sky meteor radar in my country is not comprehensive, and the timeliness, accuracy and resolution need to be improved; The present invention starts from the original signal detected by the all-sky meteor radar, aims at establishing a complete all-sky meteor radar analysis and processing system and obtaining high-resolution background atmospheric parameters, investigates the main flow and key technologies of radar signal analysis and processing, and realizes the all-sky The analysis and processing algorithm of meteor radar obtains the data products detected by all-sky meteor radar, which impels the establishment of my country's independent all-sky meteor radar analysis and processing system; the present invention establishes a meteor radar signal preprocessing algorithm and realizes the phase correction of echo signals , Judgment and screening of under-dense meteor events, precise positioning of meteor trails and inversion of observation parameters to realize the analysis and processing of all-sky meteor radar.

Description

technical field [0001] The invention belongs to the technical field of radar, and in particular relates to an analysis and processing method and system based on all-sky meteor radar signals. Background technique [0002] A meteor trail is a long, dense column of plasma created by a meteoroid entering the Earth's upper atmosphere. It stays in the background atmosphere, has a strong scattering effect on radio waves, and can be tracked by radar, providing a perfect natural tracer for the detection blind zone of the mesosphere and low thermosphere (MLT region). Meteor radar is a very important MLT area detection method that takes meteor trails as the observation object. Because of its simple equipment, moderate cost, all-weather, all-weather, long-term stable observation, and high measurement accuracy, it has become one of the conventional observation methods in the MLT area and plays an indispensable role in the atmospheric research in the MLT area. Atmospheric wind field can...
