A moving target detection method for airport surface surveillance radar system

Abstract

The invention discloses a moving target detection method used for an airport scene surveillance radar system. The method comprises the following steps of acquiring the target echo information of an ith frame after radar front end processing; carrying out false point trace filtering processing and channel maximum selection processing on the target echo information of the ith frame; according to thetarget echo information of the ith frame after channel maximum selection, forming the two-dimensional image of the ith frame and carrying out target edge extraction; carrying out inter-frame differential processing according to the two-dimensional image of the ith frame and the two-dimensional image of an i-1th frame; and according to the inter-frame differential processing, acquiring the targetecho information of the ith frame belonging to a moving target and the target echo information of the ith frame belonging to a same target after the target edge extraction, carrying out matching processing, and acquiring the target echo information of the ith frame belonging to a same moving target. A moving target real-time detection problem is solved, the detection precision of the airport scenesurveillance radar system to the moving target is increased, and reliable data is provided for the subsequent cohesion of the moving target.

Description

technical field [0001] The invention relates to the technical field of real-time detection of a moving target in an airport scene surveillance radar system, in particular to a method for detecting a moving target in an airport scene surveillance radar system. Background technique [0002] With the rapid development of my country's economy, the number of flights is also increasing rapidly, which puts forward higher requirements for the command of air traffic control system controllers and the maintenance of facilities and equipment. The airport surface surveillance radar is mainly used to monitor the aircraft and vehicles on the airport scene. Using the target's own radiation or reflection characteristics of electromagnetic waves to find the target can make the airport tower controller's surveillance of the aircraft no longer restricted by the line of sight, and can accurately monitor the airport even in the dark and inclement weather conditions. Aircraft and ground vehicles ar...
