Abstract

A radar system for detecting a single object from a plurality of objects and calculating 4D information of said object may include a first radar for obtaining first positional information of a first object, a second radar for obtaining second positional information of a second object and a computer for comparing the first positional information with the second positional information to determine if the first object is the same as the second object and combining the matched first positional and second positional information into 4D information.

Claims

1. A radar system for detecting a single object from a plurality of objects and calculating 4D information of said object, comprising:

a first radar for obtaining first positional information of a first object;

a second radar for obtaining second positional information of a second object;

a computer for comparing the first positional information with the second positional information to determine if the first object is the same as the second object and combining the matched first positional and second positional information into 4D information.

2. A radar system for detecting a single object from a plurality of objects and calculating 4D information of said object as in claim 1, wherein the first radar is a horizontal radar.

3. A radar system for detecting a single object from a plurality of objects and calculating 4D information of said object as in claim 1, wherein the second radar is a vertical radar.

4. A radar system for detecting a single object from a plurality of objects and calculating 4D information of said object as in claim 1, wherein the first positional information includes range information.

5. A radar system for detecting a single object from a plurality of objects and calculating 4D information of said object as in claim 1, wherein the second positional information includes range information.

6. A radar system for detecting a single object from a plurality of objects and calculating 4D information of said object as in claim 1, wherein the first positional information includes azimuth angle information.

7. A radar system for detecting a single object from a plurality of objects and calculating 4D information of said object as in claim 1, wherein the second positional information includes elevational angle information.

8. A radar system for detecting a single object from a plurality of objects and calculating 4D information of said object as in claim 1, wherein the first positional information includes range rate information.

9. A radar system for detecting a single object from a plurality of objects and calculating 4D information of said object as in claim 1, wherein the second positional information includes range rate information.

10. A radar system for detecting a single object from a plurality of objects and calculating 4D information of said object as in claim 1, wherein the first positional information being compared to the second positional information includes first range information from the first radar being compared to second range information from the second radar.

11. A radar system for detecting a single object from a plurality of objects and calculating 4D information of said object as in claim 1, wherein the first positional information being compared to the second positional information includes first range rate information from the first radar being compared to second range rate information from the second radar.

12. A radar system for detecting a single object from a plurality of objects and calculating 4D information of said object as in claim 1, wherein the matched first positional information and second positional information is combined into 4D information.
