High-speed signal processing system and signal processing method thereof for scene monitoring radar

Abstract

The invention belongs to the technical field of radar signal processing and particularly relates to a high-speed signal processing system and a signal processing method thereof for a scene monitoringradar. The system comprises an extension set system A and an extension set system B. The extension set system A and the extension set system B are completely identical in structure. The extension setsystem A and the extension set system B are a redundant backup for each other. The extension set system A and the extension set system B are in two-way communication connection with each other. The extension set system A and the extension set system B are in two-way communication connection with a duplex switch. The duplex switch and the antenna are in two-way communication connection with each other. When a certain device in one set of the radar breaks down, the system automatically re-configures the function. Therefore, the performance of the system is not reduced at all, and the reliabilityof the system is enhanced. The system disclosed by the invention is high in distance and azimuth resolution, and can be continuously operated for a long period of time. Meanwhile, the seamless switching between different modules can be facilitated, and the visibility of an airport can be detected quickly, reliably and accurately. The operation efficiency and the safety level of the airport underany weather condition are guaranteed. The operation efficiency of the airport is improved.

Description

technical field [0001] The invention belongs to the technical field of radar signal processing, in particular to a high-speed signal processing system and a signal processing method for surface monitoring radar. Background technique [0002] In recent decades, the development of the global aviation industry has been quite rapid. The scale of domestic airports has grown day by day, resulting in a sharp increase in the number of aircraft take-offs and landings in the airport, and the passenger flow is also increasing. This will inevitably lead to the number of activities of aircraft and ground service vehicles in the airport. more often. In the ground activity area of ​​the airport, there is a certain distance between ground aircraft and motor vehicles and the control tower, and due to the occlusion of the sight of the airport staff and the low visibility and bad weather conditions such as heavy fog and night vision, the aircraft takes off, The probability of operational conf...

AI Technical Summary

Problems solved by technology

[0004] In order for the surface control personnel to grasp the ground information of the airport in a timely manner, the surface surveillance radar needs higher real-time and high detection accuracy to ensure the safe operation of the airport scene. The existing high-speed signal processing system for the surface surveillance radar cannot operate in harsh conditions Rapid, reliable and accurate detection of airport visibility under weather conditions, which cannot guarantee the operational efficiency and safety level of the airport
