Problems solved by technology

[0006] The purpose of the present invention is to provide a track processing method and system of an airport surface surveillance radar, which associates and tracks the track data obtained by the scene surveillance radar to form the track data of the surveillance target, aiming at solving the problem of existing radar The non-surveillance targets in the point-track processing method will generate false alarms, and it is easy to cause track jitter and correlation interruption. At the same time, the algorithm is relatively complex, the calculation is large, and it is difficult to realize the problem of engineering

specific Embodiment 1

[0088] Such as figure 1 As shown, the embodiment of the present invention shows a spot processing method of an airport surface surveillance radar, which includes the following steps.

[0089] Initialization step S101, setting the initial masked area of ​​the track in the monitoring area; establishing a temporary track for all measured points outside the initial masked area of ​​the track; storing each confirmed track in advance. This step establishes a temporary track for all measured points outside the masked area of ​​the track, where the temporary track can be a small initial section, and establishes an association threshold according to the maximum possible speed of the target movement in the monitoring area, and then the second During the detection period, a temporary track is established according to the threshold.

[0090] Actual measurement step S102, obtaining actual measurement points of the monitoring target.

[0091] Prediction step S103 , predicting the establis...

specific Embodiment 2

[0112] Such as figure 2 As shown, the embodiment of the present invention provides a spot processing system of an airport surface surveillance radar, comprising:

[0113] Initialization module 201 is used to set the initial shielding area of ​​the track in the monitoring area; establish a temporary track for all measured points outside the initial masking area of ​​the track; store each confirmed track in advance;

[0114] The actual measurement module 202 is used to obtain the actual measurement points of the monitoring target;

[0115] Prediction module 203, is used for predicting the temporary track of establishment, obtains each temporary track prediction point;

[0116] The confirmed track association module 204 is used for associating and judging the actual measured point of the monitoring target and each confirmed track prediction point respectively; when the association is successful, the measured point of the monitored target is added to the confirmed track of the s...

Abstract

The invention provides a point track processing method and system of an airport surface monitoring radar. An actual measurement point is associated with a determined track; if association is done successfully, the determined track after newly adding of the actual measurement point is outputted; if the actual measurement point can not be associated with the determined track, the actual measurementpoint is associated with a temporary track; if association is done successfully, whether the temporary track after newly adding of the actual measurement point meets a flight track conversion requirement and whether a speed requirement is met are determined; and if so, the temporary track is converted into a determined track and the determined track is outputted. According to the invention, a false alarm generated by a non-monitoring target can be eliminated; the track association is stable, the calculation load is small, and the engineering is easy to realize.

Description

technical field [0001] The invention relates to the technical field of radar track processing and analysis, in particular to a point track processing method and system for an effective airport surface surveillance radar. Background technique [0002] The main process of radar point track data processing is to establish track according to the point track obtained by scanning the target every time according to the movement of the target, so as to track the target. It mainly includes track initiation, track correlation, and target tracking and prediction. At present, there are many researches in various fields. The design scheme of the system trajectory. [0003] The methods of track initiation mainly include intuition method, logic method, hough transform method and so on. The principle of the intuition method is based on the motion characteristics of the target. It is believed that the position of the same target in two radar scans is determined by its motion speed. A circu...
