Abstract

A method for traffic monitoring, particularly at airports, is disclosed including the localization of a traffic object is carried out by direction finding and by additional information. The radio communication between the traffic object and a control center is recorded and fed to a speech recognition unit on the side of the control center; an identification phrase transmitted together with the message of the traffic object is identified in the speech recognition unit on the side of the control center and allocated to the localized traffic object; and that the allocated identification of the localized traffic object is continuously maintained, the source of the identification being on the side of the traffic object.

Claims

1. Method for traffic monitoring of a traffic object comprising the steps of:

localizing the traffic object by direction finding utilizing a single direction finding antenna and by means of additional information;

recording a radio communication between said traffic object and a control center and feeding the communication to a speech recognition unit on the side of said control center;

identifying an identification phrase which is transmitted together with the communication of said traffic object by said speech recognition unit on the side of said control center and which is allocated to said localized traffic object; and

continuously maintaining said allocated identification of said localized traffic object, the source of said identification being on the side of said traffic object.

2. Method according to claim 1, wherein an unequivocal allocation between a position of the traffic object and said identification is carried out and, in case of a recognized discrepancy within said allocation on the side of said control center any one of a manual correction, an oral request and an automatic request is transmitted to said traffic object for a repetition of any one of an oral and automatic transmission of said identification phrase.

3. A system for traffic monitoring traffic objects, comprising:

a single direction finding installation for measuring the direction to the traffic objects upon the traffic objects transmitting a radio message;

a primary installation for processing additional data relating to the localization of the traffic objects;

a communication installation for communication between said traffic objects and a control center;

a speech recognition unit on the side of said control center for speech recognition of radio messages of said traffic objects and optionally of said control center;

a data processing unit;

a connection between said data processing unit and said direction finding installation and primary installation for localization and said speech recognition unit; and

wherein said data processing unit has means for fusion of input data for the allocation of unequivocal location and identification of said traffic objects and for transmission of the allocation results to an output unit.

4. The system according to claim 3, wherein, said single direction finding installation for the localization of traffic objects comprises a single direction finding unit or direction finding antenna for measuring the direction of the communication transmission.

5. The system according to claim 4, wherein, said primary installation comprises a primary radar which is provided together with said direction finding unit or said direction finding antenna for measuring the direction of said incoming radio transmissions from said traffic objects.

6. A system for traffic monitoring traffic objects, consisting of:

a single direction finding installation for measuring the direction to the traffic objects upon the traffic objects transmitting a radio message;

a primary installation for processing additional data relating to the localization of the traffic objects;

a communication installation constructed and arranged to provide communication between said traffic objects and a control center;

a speech recognition unit on the side of said control center constructed and arranged to provide speech recognition of radio messages of said traffic objects;

a data processing unit;

a connection between said data processing unit and said direction finding installation and primary installation for localization, and said speech recognition unit; and

wherein said data processing unit includes means for fusion of input data for the allocation of unequivocal location and identification of said traffic objects and for transmission of the allocation results to an output unit.
